Comparison Jabra Mini vs Jabra Style

The design of the earpiece used in a Bluetooth headset.

— Earbuds. A small earpiece located in the auricle outside the auditory canal (as opposed to in-ear). The unequivocal advantages of inserts are simplicity and low cost. The sound insulation of such devices turns out to be rather weak, which can be both a minus and a plus: the earbud is not suitable for a noisy environment, but it almost does not interfere with hearing. But the sound quality of the earbuds is somewhat lower than that of the in-channel counterparts. In addition, such an earpiece is less securely held in the ear and is more difficult to adjust to the individual biological nuances of a person (although interchangeable nozzles of different sizes are available for the earbuds).

— In-ear. An earpiece that, during use, is inserted deep into the ear canal and held there by a soft cap made of silicone or other similar material. These headphones are considered more advanced than earbuds: at lower volume (and less power consumption), they provide more powerful and rich sound. The unequivocal disadvantages of in-ear models include a higher cost. In addition, a high degree of sound insulation can create inconvenience: when using such headsets, ear is almost completely closed. On the other hand, it allows you to hear the sound well even in a rather noisy environment.

The nominal impedance of the earpiece or speaker installed in the device. This parameter is indicated in the specifications extremely rarely, and even in such cases it is purely for reference: the hardware of the device is initially optimized for the corresponding headphone/speaker impedance.

The diameter of the speaker installed in the device. In this case, we can talk about both the actual speaker installed in the speakerphone, and the headphone emitter that the Bluetooth headset is equipped with (see "Device"). Accordingly, the meaning of this spec in both cases will be different.

In general, the large size of the speaker, on the one hand, allows you to achieve better volume and more reliable transmission of low frequencies; on the other hand, it requires more space for installation. This is especially true for headsets, since the types of headphones used in them (see "Design") have severe size restrictions: earbuds are made no larger than 15 mm, in-ear solutions have a diameter of less than 10 mm (only the headphones of the same type may be compared by size with each other). Note that an earpiece that is too large may be uncomfortable, or even not fit in the ear at all. So the perfect option is to try on the headset before buying.

In turn, speakerphones usually use speakers with a diameter of about 50 mm — this size is considered the best compromise between overall efficiency and compactness.

— Multipoint. A feature of Bluetooth devices (see "Connection") that allows them to connect to multiple signal sources at the same time. Thanks to this, it is possible, for example, to use one headset both for answering phone calls and for chatting via Skype on a laptop. However, some mobile phones (mostly devices with the simplest functionality, not smartphones) do not support this feature and are not able to work with a headset connected simultaneously to another gadget.

— Noise reduction. A feature that allows the headset microphone to "hear" only the necessary sounds (primarily speech) and filter out extraneous noise. The specific implementation of noise reduction can be different: some models provide an additional microphone that tracks noise and "cancels" it from the final signal, while others use purely software methods of sound cleaning. Anyway, such filtering significantly improves the audibility for the person at the other end of the line.

— Volume control. Own volume control built right into the device. Adjusting the sound in this way is usually more convenient than reaching into your pocket for your phone, changing settings on a laptop, etc. On the other hand, an additional control affects the compactness. Therefore, among Bluetooth headsets (see "Device") this feature is not always provided; but for speakerphones that do not have special restrictions on dimensions, it is alm...ost mandatory.

— Auto volume control. Automatically adjust the volume at which the device plays sound. Adjustment is usually carried out according to the level of ambient noise: in a quiet environment, the volume is reduced so as not to create discomfort, and in a noisy environment it is increased, ensuring normal hearing. Many models use the same microphone for auto-adjustment as noise canceling systems (see above), although this feature is not necessarily combined with noise canceling.

— Voice dialing. The ability to dial numbers by voice command, voiced into the microphone of the device. This feature is especially useful if you need to make a call, but reaching for the phone is undesirable or impossible — for example, when driving. Therefore, voice dialing is extremely popular in car kits (see "Device"), models without this feature are extremely rare. This feature is also supported by numerous Bluetooth headsets. However to use voice dialing, it must also be supported by the gadget to which the headset or car kit is connected; however, modern smartphones and tablets have no problems with this, difficulties can arise only with some models of classic mobile phones (non-smartphones). But language support in voice dialing needs to be specified separately: English is available in almost any model, but other languages are not so common.

— Microphone mute. The ability to temporarily mute the device's microphone — usually by pressing a special button. This will be useful in case you need to say something "to the side" and you do not want the person on the line to hear you. Note that the built-in microphone mute function is available in almost all mobile phones, as well as in most programs for voice communication like Skype. However, using the button on the headset is often more convenient than going into the settings of a smartphone or computer.

— A2DP profile. A Bluetooth connection feature (see "Connection") that allows stereo sound to be transmitted. A2DP support is by definition available on Bluetooth accessories that support stereo (see Audio). At the same time, this profile can also be provided in conventional one-ear headsets — it allows such a headset to normally reproduce sound originally recorded in stereo format (for example, podcasts or audio books), and is also used when headphones are connected (see below). Anyway, to use A2DP, it must be provided in both the accessory and the main device. Therefore, if you, for example, are looking for a headset for a simple phone that does not have A2DP, you can choose a model without this feature.

— AVRCP profile. Bluetooth connection feature (see "Connection"), which turns the accessory into a wireless remote control. To be more precise, we are talking primarily about managing audio and video players: start / pause playback, switch tracks, rewind, etc. At the same time, this feature can be provided even in Bluetooth headsets for one ear, which are not intended for music at all — for example, with such a headset you can control the music played from your smartphone through a portable speaker. Of course, AVRCP can only be used if both Bluetooth devices support it.

— NFC. NFC is a short-range wireless communication technology with a range of up to 10 cm. In Bluetooth accessories, the main purpose of this technology is to speed up the connection: instead of digging through the settings, just bring the accessory with NFC to a gadget that has the same chip (smartphone, tablet, etc.) and confirm the connection; and many gadgets allow you to configure and automatically connect when approached. There are other options for using NFC, but in this case they are practically not found.

— Display. Own display, which can show various service information: battery charge, volume level, connection indicator, etc. The specific capabilities of such a screen may vary depending on the type of accessory (see "Device"). However, most models with this feature are car kits — they can provide a fairly large screen with extensive information options, such as showing the number of an incoming or outgoing call. In headsets, screens are extremely rare: after all, most of the time the device is on the ear, out of the user's field of vision.

— Headphone jack. It's for connecting traditional headphones to the device. Most often, such a connector is a standard 3.5 mm mini-Jack, used in most modern headphones, which provides very extensive connection options. But the purpose and capabilities of this connector depend on the type of accessory (see "Device"). So, most models with this feature are speakerphones, and you can connect both regular headphones without a microphone, and wired headsets with their own microphone; both of them are used mainly to ensure the privacy of the conversation. But Bluetooth headsets are usually only compatible with headphones without microphones, and such headphones are used mainly for listening to music — you can talk privately on the phone using the headset itself.

The type of power used by the device. This parameter is indicated only for models with an independent power source: these are absolutely all Bluetooth headsets (see "Device"), as well as most speakerphones and some car kits (the last two varieties can also be powered from an external source — for example, from the on-board network of a vehicle or USB port).

Almost all self-powered devices run on built-in batteries, often non-removable ones. Such batteries can be made small and at the same time capacious, and their shape can be different — this makes it easy to integrate such a power source even into a miniature headset, not to mention larger accessories.

Time of operation of the self-powered device (see "Power") on one battery charge.

Usually, the battery life in the talk mode is meant, when the device consumes the most energy. In headsets with high-capacity batteries, this battery life can be 9 hours or more. However, talking for several hours without pauses is almost impossible, so in fact the operating time is noticeably longer than in the specifications. So, a headset with an operating time of the same 9 hours is most likely quite enough for a 12-hour work shift, even if you have to constantly make calls through it; and if we are talking about only 5 – 6 calls per day, then the charge is guaranteed to last for several days, or even a week. At the same time, the difference in the claimed operating time is usually quite consistent with the difference in actual battery life, and it is quite possible to compare the real capabilities of different models by it.

The type of connector used to charge the built-in battery of Bluetooth headsets, more precisely, to connect an external charger. The role of such a device can be played by a network or car adapter, a power bank, or even a USB port on a PC or laptop (if you have the appropriate cable).

— microUSB. A smaller version of the USB connector designed for portable devices. It appeared quite a long time ago, but it does not lose popularity nowadays, despite the active implementation of the USB-C port.

— USB-C. A miniature USB connector, positioned, among other things, as a potential successor to microUSB. Unlike its predecessor, it has a double-sided design, thanks to which the plug can be inserted into the socket in either direction. It is still relatively rare, but the situation is likely to change in the coming years.

You can change the ear hook that is used to attach the Bluetooth headset to the ear. This feature allows you to adjust the device to the features of the auricle, which is especially necessary for people with a non-standard size or shape of the ears. Usually spare temples are included in the package, and if necessary, they can be purchased separately.

Replaceable silicone tips that come in a box with with the Bluetooth headset (see "Device").

Modern headsets are traditionally equipped with in-ear headphones or earbuds (see "Design"); both of them are held in the ear by a soft attachment, usually made of silicone. The size of such a tip may not be suitable for the user — in this case, the ability to change it to another, more convenient one, will be essential. Most often, there are three replaceable tip in the kit — large, regular and small.
