Glossary
Design
This item primarily specifies the way headphones are mounted on the ears; by this parameter, modern headphones are divided into over-ear, in-ear, earbuds, open-ear types. For over-ear models, it may also specify the acoustic design (closed, semi-open, open), as well as the presence of features such as over-ear construction (in the absence of this feature such headphones are called on-ear, or just "on-ear"), swivel cups, auto headband adjustment or even the popular mid-2021 trend — Cat Ear Headphones (headphones with cat ears). Details such as a rigid band, over-the-ear mounting, neck mounting, and folding ability, can be combined with almost any method of ear placement (with some exceptions — for example, on-ear models cannot be worn on the neck).
Here is a more detailed description of different ear placement options:
— On-ear. On-ear headphones are placed outside the auditory pinnae, covering the ear from the side ("usual" on-ear models) or completely (full-size Over-Ear — see below). In any case, such models are fairly large. This, on the one hand, simplifies the creation of headphones w...ith advanced audio characteristics, and also allows using some specific tricks without much difficulty — for example, multiple drivers or multichannel surround sound support. On the other hand, the size of the "ears" complicates transportation and use on the go. Moreover, it should be noted that most on-ear models feature a headband, making them less compatible with complex hairstyles and some headgear. This disadvantage is absent in models with rigid bands and over-the-ear mounts, but they also have their specifics (see below).
On-ear headphones can have different acoustic designs:
— In-ear with a rigid band. In-ear headphones are placed inside the ear canals, allowing them to be most securely fixed in the ear and not fall out. The presence of a rigid band further increases the reliability of the headphones' fixation. This type of headphones is well-suited for sports. The rigid band and in-ear design of sound emitters allows the headphones to stay securely in place even during intensive running.
— Earbuds. Also colloquially known as "pills." Similar to in-ear models, such headphones are small and placed in the auditory pinna — but not deep in the ear canal, just at its entrance, almost outside. As a result, earbuds are somewhat simpler in construction and cheaper, but achieving rich sound and advanced acoustic characteristics is more challenging with them. Such models provide quite low sound isolation, but this can be either a downside or an advantage — depending on the situation. Some headphones of this type have an elongated shape, allowing them to sit deeper in the ears and approaching in-ear models in capabilities.
It is worth noting separately that in-ear models and earbuds don't use headbands — the headphones are made either completely separate or connected by a device such as a rigid band or neck mount. Thus, such headphones can easily be worn with almost any hairstyle or headgear.
— Earbuds with a rigid band. Earbuds are simply inserted into the ear canal entrance, not penetrating deeply. This is not the most reliable way to fix the headphones, but due to the presence of a rigid band, earbuds gain secure placement and reliable fixation. The headphones themselves have an open sound path design, which reproduces audio with noticeable distortion to the original sound signal. However, the open acoustic scheme allows clear hearing of the surrounding environment.
As for additional design features, they can be such:
— Full-size Over-Ear. On-ear headphones (see above) in which each cup completely covers the ear and fits tightly against the head. Cups in such models are made fairly large and equipped with characteristic soft "borders" along the inner side's perimeter — these borders fit tightly against the head, so the ear pinna is effectively inside the cup. The main advantage of such a design is that the headphones (with the right size) practically do not touch the user's ears and do not press on them — this is particularly comfortable for extended use. Furthermore, Over-Ear models facilitate achieving high-quality sound isolation (although among them it is possible to find models with semi-open and even completely open acoustic design). The main disadvantage of such devices is bulkiness and inconvenience in transport and on-the-go use. Additionally, when wearing glasses, Over-Ear cups usually press on the frames' sides — this can cause discomfort.
— Open-ear. A special variety of wireless true wireless headphones with open acoustic design. Unlike earbuds and in-ear models, open-ear headphones do not suggest partial or full closure of the auricle — this provides better perception of surrounding sounds. This is handy during walks and outdoor runs. Most often, such headphones have over-the-ear mounts (see below), and the drivers in their construction are directed straight into the ear canals but remain outside. Passive noise isolation in open-ear headphones is practically absent, and the playing music and phone conversations may be heard by those nearby — keep this in mind.
— Auto headband adjustment. A headband capable of automatically adjusting to the user's head size. Such a headband usually consists of two parts — a rigid, usually metallic, base and a soft inner part that fits directly against the head. The inner part is capable of stretching, and the user just needs to place the cups on the ears comfortably — and the headband will automatically adjust to the needed size.
— Rigid band. A band made of rigid material, connecting the two headphones and worn on the back of the head; in some models, it can also serve as a neck mount (see below). The advantage of such a device over a classic headband is that the band can be used with almost any hairstyle and headgear. On the other hand, in in-ear models and earbuds (see above), this feature makes the headphones bulkier, and in on-ear models, it makes sense to use it only with regular models, not belonging to full-size Over Ear. Consequently, for a range of reasons, the band is not particularly popular nowadays.
— Over-the-ear mounting. A mount that allows fixing each headphone directly on the auricle; it generally has the form of a characteristic band. This feature appears in all types of modern "ears," except Over Ear (see above), and its specific meaning depends primarily on the main method of placing the headphone on the ear. For in-ear models and earbuds, over-the-ear mounting provides additional retention reliability: the likelihood of the headphone falling out of the ear is practically reduced to zero due to such a mount. In on-ear "ears," this feature appears significantly less often, and its main purpose is to do without a headband or rigid band — in some cases, these construction elements are unnecessary.
— Neck mounting. A feature found exclusively in wireless and combined models (see "Connection Type") — and only in in-ear and earbuds (see above). Both headphones in such models are connected by either a regular wire with a thickened part or a special horseshoe-shaped band (to each end of this band, an individual "ear" is connected via a wire). In any case, during use, this wire or band is located behind the user's neck, ensuring additional convenience: removed from the ears (or fallen out), headphones do not drop to the ground but remain hanging on the mount. Some models also feature special magnets, enabling the removed headphones to "stick" together, turning the entire structure into a ring — reducing the risk of dropping the device even further.
— Folding ability. The ability to compactly fold headphones for storage and transportation. Note that this feature is listed only for on-ear models (see above) — in-ear headphones and earbuds are already quite portable by themselves, without a special folding design.
— Swivel cups. A design feature found in on-ear headphones (see above). Swivel means cups that, in working position, can rotate at a certain angle around the vertical axis. This allows headphones to further adjust to the user's head size and shape — thereby increasing comfort, especially during prolonged wear. On the other hand, the swivel mount slightly complicates the headphones' construction, increases the cost, and somewhat reduces reliability.
Here is a more detailed description of different ear placement options:
— On-ear. On-ear headphones are placed outside the auditory pinnae, covering the ear from the side ("usual" on-ear models) or completely (full-size Over-Ear — see below). In any case, such models are fairly large. This, on the one hand, simplifies the creation of headphones w...ith advanced audio characteristics, and also allows using some specific tricks without much difficulty — for example, multiple drivers or multichannel surround sound support. On the other hand, the size of the "ears" complicates transportation and use on the go. Moreover, it should be noted that most on-ear models feature a headband, making them less compatible with complex hairstyles and some headgear. This disadvantage is absent in models with rigid bands and over-the-ear mounts, but they also have their specifics (see below).
On-ear headphones can have different acoustic designs:
- Closed. Models with a high degree of sound isolation, maximally shielding the user from external sounds. This design contributes to rich sound (especially in the bass range) and provides a very powerful immersion effect, making it suitable for home use (including computer games) and noisy environments. However, using such "ears" on the street is not recommended: full isolation from surrounding sounds in such conditions can be unsafe. Besides, it is believed that a fully closed design slightly worsens sound fidelity.
- Open. Headphones with minimal sound isolation, allowing most external sounds through. They are less powerful and rich in sound compared to closed models and less effective in noisy environments; also, the sound from such headphones is easily heard by those around. On the other hand, open models generally provide more authentic sound and are better suited for situations where it's necessary to monitor the surrounding environment — for example, for use on the street.
- Semi-open. A kind of compromise between the above-described options: headphones with better sound isolation than open models but still not reaching the level of closed "ears." For some users, this intermediate option may be more comfortable. Additionally, semi-open headphones are valued in professional sound work: they retain bass richness and at the same time do not create the distortions characteristic of a fully closed design.
- With a rigid band. A rigid band allows the earbuds to be reliably fixed to the auditory pinnae. A close analogue of the rigid band is the headband of full-size headphones, but unlike that, the band is worn on the back of the head, not the top. For this reason, rigid bands are mostly made without soft padding, from bare plastic/metal. Headphones with a rigid band most often have a sporting focus, as being on the back of the head, they will not slip even during intense running. On-ear headphones are closely pressed to the auditory pinnae, but the speakers themselves are placed outside the ear canals.
- Cat Ear ("ears"). On-ear headphones in an interesting design — with imitation cat ears on the headband. This addition does not affect working characteristics but looks unusual and can be a great addition to the owner's vibrant, original style. Cat Ear Headphones are particularly popular among teenagers.
— In-ear with a rigid band. In-ear headphones are placed inside the ear canals, allowing them to be most securely fixed in the ear and not fall out. The presence of a rigid band further increases the reliability of the headphones' fixation. This type of headphones is well-suited for sports. The rigid band and in-ear design of sound emitters allows the headphones to stay securely in place even during intensive running.

Connection
The specific connection interface provided in the headphones. At the same time, some models may provide several options at once - these are either combined devices (see “Connection type”) or wired headphones equipped with additional adapters.
— micro-Jack (2.5 mm). A wired connector similar to the popular mini-Jack 3.5 mm (see below), but smaller in dimensions. Equipment with such a connection is rare - they are mostly miniature devices, where there is simply no room for a 3.5 mm connector. Accordingly, this interface has not become widespread among headphones: it is almost never found in its pure form; models with such a plug are usually supplemented with an adapter or cable for a mini-Jack.
— mini-Jack(3.5 mm). Perhaps the most popular modern type of audio connector; If a device claims to have a headphone output, most likely it is a 3.5 mm jack. Accordingly, most headphones with a wired connection use this type of connector. It is worth noting that headphones with a microphone designed for such a connection are equipped with a special plug for a combined headphone + microphone audio connector (similar connectors are popular in portable gadgets and laptops). But with a jack intended only for “ears” without a microphone, such a plug may not work correctly. An alternative could be headphones equipped with two separate mini-jack plugs; See below for more details on this option.
— mini-Jack (2 x 3.5 mm).... Models with two 3.5 mm mini-jack plugs. This option is guaranteed to mean that we are not talking about classic headphones, but about a headset with a microphone: one plug is used for headphones, the second for a microphone. Such models are convenient when used with equipment that has separate 3.5 mm jacks for “ears” and a microphone - for example, for a PC.
— Pentaconn (4.4 mm). It is a 5-pin balanced output. Pentaconn uses a larger plug compared to the mini-Jack; its size is 4.4 mm, which is stronger and more reliable than the 3.5 mm connection. Pentaconn's balanced connection makes it possible to work with high-power audio signals. Thanks to this connection, it is possible to transmit a signal over a fairly long distance. Accordingly, such a connector is relevant for headphones of the highest category.
— Jack (6.35 mm). The largest type of Jack-type audio connector found in modern technology. Outputs of this type are found mainly in stationary audio equipment - for portable devices they are too bulky, where it is easier to use a 3.5 mm mini-jack. At the same time, the 6.35 mm connector is considered a more suitable interface for professional and audiophile-grade equipment: it provides a more reliable connection, greater contact density and, accordingly, less likelihood of interference. Therefore, although relatively few headphones (mostly premium solutions) are equipped with their own Jack type connector, many models with a 3.5 mm mini-Jack plug are equipped with an adapter to 6.35 mm.
- XLR. A characteristic round connector with a locking lock and 3 contacts (there are other options for quantity). Typically, it is used to transmit an analog signal over a balanced connection. This connection provides high immunity to interference, typical for professional use; at the same time, the connector itself has quite large dimensions. In view of all this, the presence of XLR is relevant mainly for headphones designed for use with advanced stationary equipment.
— Bluetooth. The most popular wireless connection option in modern headphones. This is due to the fact that built-in Bluetooth modules are available in almost any modern smartphone, tablet or laptop, and appropriate adapters can be produced for devices without this module (for example, a PC). True, the sound quality with a traditional Bluetooth connection is relatively low, but to correct the situation, special technologies like aptX and aptxHD are increasingly being used (see “Codec support”).
It is also worth noting that Bluetooth modules can correspond to different versions (the latest for 2022 are Bluetooth 5.0, Bluetooth 5.1, Bluetooth 5.2, Bluetooth 5.3, Bluetooth 5.4). This point does not affect the sound quality, but it determines a number of additional nuances - communication range and reliability , the ability to work through walls and other obstacles, resistance to interference, etc. In modern “ears” you can find the following versions of Bluetooth:
- IR channel. Another method of wireless connection, the peculiarity of which is that it does not use radio waves, but infrared radiation. Theoretically, the advantage of such a connection is its resistance to electromagnetic interference, the disadvantage is that it only works in line of sight. In practice, the situation is such that in most cases it is easier to use Bluetooth or a radio channel for a wireless connection. So this option is found exclusively in specialized devices for equipment equipped with their own IR outputs - in particular, among headphones for car monitors.
— USB-A. Wired connection to a standard (full-dimensions) USB connector. This option is found exclusively among headphones designed for computers/laptops or gaming consoles. One of its advantages is that sound via USB is transmitted digitally and is processed not by the computer's audio card, but by the built-in headphone converter; such a converter often provides better sound quality than the mentioned audio card. In addition, multi-channel audio can be transmitted via a USB connection - this point will be especially appreciated by gamers. Another advantage is that when using USB headphones, specialized audio outputs remain free, and you can connect other equipment to them - for example, computer speakers or a vibration pad.
- USB-C. A relatively new type of USB connector, used in both desktop computers and portable devices - as a successor to microUSB. It is not very different in dimensions, but has a more advanced design - in particular, it is made double-sided, which makes connection easier. Most often complemented by other connection options (they can be either wired or wireless).
- Lightning. A universal connector used in Apple portable devices - iPhone smartphones and iPad tablets - since 2012. Not used by other manufacturers. Accordingly, models with such an interface are designed specifically for Apple technology (primarily iPhone and iPod touch players). This type of connection is especially relevant given the fact that in the latest iPhones the manufacturer has completely abandoned a separate audio output, and the only option for connecting headphones is the Lightning port.
— Branded connector. A connection connector that does not belong to generally accepted standards and is used to a limited extent in equipment from one or several manufacturers. Such connectors are found mainly among headphones for mobile phones. However, due to general standardization, this option has practically disappeared from the scene. Theoretically, the branded connector is also the Lightning described above, but it is separated into a separate category due to the popularity of Apple technology.
— micro-Jack (2.5 mm). A wired connector similar to the popular mini-Jack 3.5 mm (see below), but smaller in dimensions. Equipment with such a connection is rare - they are mostly miniature devices, where there is simply no room for a 3.5 mm connector. Accordingly, this interface has not become widespread among headphones: it is almost never found in its pure form; models with such a plug are usually supplemented with an adapter or cable for a mini-Jack.

This point does not affect the sound quality, but it determines a number of additional nuances - communication range and reliability , the ability to work through walls and other obstacles, resistance to interference, etc. In modern “ears” you can find the following versions of Bluetooth:
- Bluetooth v 4.0. An update in which the capabilities of version 3.0 (classic + high-speed Bluetooth) were supplemented with a third format - Bluetooth LE (low energy consumption). This communication standard is intended mainly for transmitting small amounts of information - in particular, service data packets to maintain a connection. At the same time, the creators managed to combine economical energy consumption and a long communication range - it can reach 100 m. This has a positive effect on the stability of the connection.
- Bluetooth v4.1. Development and improvement of Bluetooth 4.0. If we talk specifically about headphones, the key innovation for them in this version is improved noise immunity when working near 4G (LTE) mobile communication devices (in earlier standards, Bluetooth and LTE signals could overlap, which led to failures). So, for use with a 4G smartphone, headphones with Bluetooth support of at least v 4.1 are definitely recommended.
- Bluetooth v4.2. Further, after 4.1, development of the Bluetooth standard, which mainly introduced a number of general improvements in reliability and noise immunity.
- Bluetooth v 5.0. Major Bluetooth update released in 2016. One of the most notable innovations was the introduction of two additional operating modes of Bluetooth LE: an increased speed mode (by reducing the range) and an extended range mode (by reducing the speed). In the case of headphones, the main significance of these innovations is to improve the overall reliability of the connection, increase its range and reduce the number of dropouts.
- Bluetooth v5.1. Update version v 5.0, in which, in addition to general improvements in the quality and reliability of communication, an interesting feature has appeared, such as determining the direction from which the Bluetooth signal is coming. Thanks to this, a smartphone or other gadget that supports this standard is able to determine the location of connected devices with an accuracy of a centimeter; This can be useful, for example, for finding headphones that have disappeared from sight but are still working.
- Bluetooth v5.2. The next update, after 5.1, is Bluetooth 5th generation. The main innovations in this version are a number of security improvements, additional optimization of power consumption in LE mode and a new audio signal format for synchronizing parallel playback on multiple devices.
- Bluetooth v5.3 was introduced at the dawn of 2022. Among the innovations in it, they accelerated the process of negotiating a communication channel between the controller and the device, implemented the function of quickly switching between the operating state in a low duty cycle and a high-speed mode, and improved the throughput and stability of the connection by reducing susceptibility to interference. When unexpected interference occurs in Low Energy mode, the procedure for selecting a communication channel to switch from now on has been accelerated.
- Bluetooth v5.4. introduced at the beginning of 2023, increased the range and speed of data exchange. Also in Bluetooth v 5.4, the energy-saving BLE mode has been improved. This version of the protocol uses new security features to protect data from unauthorized access, has increased connection reliability by selecting the best channel for communication, and prevents connection losses due to interference.
- IR channel. Another method of wireless connection, the peculiarity of which is that it does not use radio waves, but infrared radiation. Theoretically, the advantage of such a connection is its resistance to electromagnetic interference, the disadvantage is that it only works in line of sight. In practice, the situation is such that in most cases it is easier to use Bluetooth or a radio channel for a wireless connection. So this option is found exclusively in specialized devices for equipment equipped with their own IR outputs - in particular, among headphones for car monitors.

It is not very different in dimensions, but has a more advanced design - in particular, it is made double-sided, which makes connection easier. Most often complemented by other connection options (they can be either wired or wireless).
- Lightning. A universal connector used in Apple portable devices - iPhone smartphones and iPad tablets - since 2012. Not used by other manufacturers. Accordingly, models with such an interface are designed specifically for Apple technology (primarily iPhone and iPod touch players). This type of connection is especially relevant given the fact that in the latest iPhones the manufacturer has completely abandoned a separate audio output, and the only option for connecting headphones is the Lightning port.
— Branded connector. A connection connector that does not belong to generally accepted standards and is used to a limited extent in equipment from one or several manufacturers. Such connectors are found mainly among headphones for mobile phones. However, due to general standardization, this option has practically disappeared from the scene. Theoretically, the branded connector is also the Lightning described above, but it is separated into a separate category due to the popularity of Apple technology.
Cable length
The length of the cable supplied with the headphones with the appropriate connectivity.
The optimal cable length depends on the planned format of the "ears". So, for pocket gadgets, 1 metre or less is often enough, for a computer it is already desirable to have a wire for 1 – 2 m, and preferably 2 – 3 m. And models with a longer cable length — 3 – 5 m or even more — are mainly designed for specific tasks, such as connecting to a TV or using in recording studios.
Recall that in some models the cable is removable (see below) and can be replaced if necessary with a longer or shorter one. Also note that there are extension cables that allow you to increase the length of the main wire; such a cable may even be included in the delivery, this point (and the length of the additional cable) is usually specified in the notes.

Cable type
The type of cable provided in the design or delivery of the headphones. Note that this parameter is relevant both for wired or combined models (see “Connection type”), and for some wireless models - in particular, earbuds and in-ear headphones without a mount, where a wire connects one earphone to another.
- Round. The classic round wire is straight, without braiding or other additional accessories. It is inexpensive and in most cases quite practical, which is why it is found in most modern headphones. The disadvantage is that if the thickness is small, the round wire is prone to tangling; therefore, this option is considered not very convenient for compact headphones, such as in-ear or in-ear (see “Design”), which often have to be carried in a pocket or bag.
- Flat. The main advantage of a flat cable is that it does not get tangled as much as a round cable, and if something happens it is much easier to untangle. This is especially important for earbuds and in-ear headphones, which are often rolled up for storage or transport. However, larger overhead models can also be equipped with a flat wire.
— Round, braided. A round wire with an outer braid, usually fabric. See above for details on round wire. And the presence of a braid gives such a cable a number of advantages over the classic one with “bare” insula...tion. Thus, the wire turns out to be more durable, reliable and resistant to kinks and pressure, tangles less, has a solid appearance, and in some models the braiding also provides shielding from external interference. The downside of these advantages is the increased price.
— Spiral. A round cable, coiled into a spring. The main advantages of a spiral wire are that it practically does not tangle and can significantly stretch relative to its original length. The latter is very convenient if, as you use your ears, you have to change the distance to the signal source. The disadvantages of spiral cable are bulkiness and relatively high cost. Therefore, it is often used in mid-range and top-end headphones (including professional models).
- Round, braided. A cable in the form of two wires twisted into a spiral. This option should not be confused with a spiral wire - in this case we are not talking about a spring. This cable is notable primarily for its unusual appearance; For greater originality, the wiring can be made in different colors. It is also somewhat more tangle-resistant than the classic round one, although a lot depends on the thickness. At the same time, individual wires can be noticeably thinner than a solid round wire, which somewhat reduces reliability.

Speaker size
The diameter of the speaker installed in the headphones; models with multiple drivers (see "Number of drivers"), usually, the size of the largest speaker is taken into account, other dimensions can be specified in the notes.
In general, this parameter is relevant primarily for over-ear headphones (see "Design"). In them, emitters can have different sizes; the larger it is, the more saturated the sound is and the better the speaker reproduces the bass, however, large emitters have a corresponding effect on the dimensions, weight and price of the headphones. But in-ear "ears" and earbuds, by definition, have very small speakers, and rich bass in them is achieved due to other design features.

Operating time (music)
The declared operating time of headphones with autonomous power supply (see above) when listening to music on a single battery charge or a set of batteries.
As a rule, the characteristics indicate a certain average operating time in music listening mode, for standard conditions; in practice, it will depend on the intensity of use, volume level and other operating parameters, and in models with replaceable batteries - also on the quality of specific batteries. However, based on the stated time, you can fairly reliably assess the autonomy of the selected headphones and compare them with other models. As for specific values, relatively “short-lived” devices have a battery life of up to 8 hours, a figure of 8 – 12 hours can be called quite good, 12 – 20 hours – very good, and in the most “long-lasting” headphones the operating time can exceed 20 hours.

Weight
The total weight of the headphones; for true wireless models (see "Cable Type"), the weight of each individual earbud is listed.
This parameter is directly related to the design (see above) and some features of the functionality. Thus, the mentioned true wireless devices are very light, their weight does not exceed 25 g. More traditional in-ears and in-ears can be noticeably heavier, up to 50g for in-ears and up to 100g for most in-ears. Overhead models, for the most part, are quite massive: among them there are many models weighing 200 – 250 g, 250 – 300 g and even more than 300 g. It should be noted that a significant weight for false ears is often not a disadvantage, but an advantage: it allows them to stay on the head more securely, creates an impression of solidity and reliability, and most often does not create significant inconvenience.

In box
Among the equipment, it is worth highlighting silicone and polyurethane tips, relevant for in-ear headphones, additional fixation nozzles and behind-the- ear arms for better attachment in the ear, interchangeable ear pads, additional cable, dongle, aircraft adapter, case / case and docking station. There are also other accessories. More details about them:
- Silicone tips. Replaceable silicone tips used in in-ear headphones. Usually, several nozzles of different sizes are supplied in the kit, which allows you to adjust the headphones to a specific user. The practical advantages of silicone are softness, durability, general convenience and at the same time low cost.
- Polyurethane nozzles. Replacement tips for in-ear headphones made of foamed polyurethane. This material is somewhat more expensive than silicone, it requires regular cleaning and has a shorter service life - including due to deformation as it wears. On the other hand, polyurethane is ideal in terms of acoustics; it is these tips that are considered the best choice for lovers of in-ear “ears” with high-quality sound.
- Ear hooks. Removable devic...es designed to additionally secure each earpiece to the ear. Note that such devices should not be confused with behind-the-ear mounts (see above). The main difference is that the arms are used exclusively in some models of in-ear headphones and earbuds as an additional option. In other words, you can wear such headphones without a bow, while the behind-the-ear mount is usually made non-removable and, in principle, you can’t do without it.
— Nozzles of additional fixation. Auxiliary caps for a tighter fit of the in-ear headphones. They are used to provide better fixation of headphones during sports or provide additional volume to users with a large auricle.
- Replaceable ear pads. Comes with interchangeable ear tips. In general, the ear pads are the part with which the headphones come into contact with the listener's ears. In full-size and on-ear headphones, they are soft pads on the inside of the cups.
— Case (case) / cover. Covers are usually called soft rag bags, they protect the "ears" mainly from pollution and take up a minimum of space. Cases are made of hard materials, they are a little more bulky, but they protect well from shock, pressure and contact with sharp objects. In any case, the complete case or case is optimally suited for the headphones and is more convenient than an impromptu protective casing.
- Charging case. Case - a case made of hard material - simultaneously playing the role of a charger. This feature is very popular on true wireless models (see "Cable Type"). The charging case usually has its own battery and the headphones are already charged from this battery; this design provides additional convenience in several moments at once. Firstly, the case, in fact, also performs the function of a power bank - an autonomous power source; the capacity of such a “power bank” may be different, but it is usually enough for several full charges of the “ears” (for more details, see “Capacity of the case”). Secondly, the ability to charge the headphones directly in the case reduces the risk of losing them. Thirdly, the charging procedure itself is quite convenient - just connect the cable to the case.
- Dock station. Stationary stand with the possibility of placing headphones and contacts for charging them. Also, docking stations are often used to transfer the sound track to headphones - they are connected directly to the sound source via a wire, and the sound is transmitted to the ears wirelessly within a certain radius of action.
— Clip for carrying. A clip designed to fasten the wire to a pocket, collar, lapel of clothing, etc. It provides additional convenience: thanks to the clip, the wire does not hang out, the likelihood of touching it with careless movement or catching on the surrounding object is reduced.
- Additional cable. An additional cable provided in addition to the main one may have different features and specializations. So, complete cables can vary in length, connector type, wire type, additional equipment (microphone, volume control), etc. These details should be specified separately in each case. Here, we note that almost all headphones with this configuration have a detachable cable (it makes sense to supplement a non-detachable wire with an extension cable, and it is considered a separate accessory - see below).
- Extension. A type of additional cable designed solely to increase the overall length of the wire. Due to the extension cord, you can adjust the headphones to the specifics of the situation: for example, “build up” the cable if you need to switch from a laptop to a TV or a stationary audio system.
— Airplane adapter. Dedicated headphone adapter for use with modern airliner entertainment systems. In such systems, a special way of connecting headphones is used - through two 3.5 mm jacks (and we are talking about classic "ears", without a microphone). Models with a traditional single 3.5 mm plug can only be connected to this output through an adapter; such adapters may initially be included in the delivery.
- Windproof microphone. Devices in the form of a foam rubber or "shaggy" lining on the headphone microphone capsule. Cut off unnecessary ambient noise and minimize the effect of direct exposure to air currents on the microphone, which can cause interference in speech transmission.
— Dongle. The dongle is used to simplify the organization of connecting wireless headphones to other devices. In fact, this is a radio transmitter (less often a Bluetooth transmitter) that non-contactly broadcasts sound to headphones from a connected device.
This list is not exhaustive and may include other optional items.
