Comparison Awei Y500 vs Awei Y200

— Bluetooth. Wireless technology for transmitting sound from mobile phones, tablets, etc. Allows connecting a device wirelessly at a short distance from the signal source. The quality and overall capabilities of Bluetooth depend on the version:

Bluetooth 4. Each version brings improvements over the previous one. For instance, version 4.0 integrated three standards: traditional Bluetooth, high-speed channel, and a power-saving mode for small data volumes. This optimized channel usage and battery consumption. In version 4.1, interference resistance was enhanced near 4G LTE modules. Version 4.2 mainly offered overall improvements in speed and security.

Bluetooth 5.0. One of the most significant innovations of the Bluetooth 5.0 standard was the expansion of the BLE ("Bluetooth Low Energy") mode capabilities: when necessary, the device can increase range by reducing speed, or speed up transmission by reducing range. Additionally, several enhancements were made for simultaneous operation with multiple connected devices.

— Bluetooth 5.1. A substantial upgrade in version 5.1 was the ability for precise positioning of the signal transmitter (receiver). While previous versions could only determine distance, version 5.1 can also determine direction. This improved navigation functionality, enhancing smart home systems, locatin...g connected devices, etc. Additionally, improvements again addressed power-saving and simultaneous operation with multiple connected devices.

— Bluetooth 5.2. The next update after 5.1 in the Bluetooth 5 generation. The main innovations in this version were a range of security enhancements, additional power consumption optimization in LE mode, and a new audio signal format for synchronizing parallel playback on multiple devices.

— Bluetooth 5.3. The Bluetooth v 5.3 wireless communication protocol was introduced at the beginning of 2022. Innovations speeded up the channel agreement process between the controller and the device, implemented fast switching between low duty cycle and high-speed mode, improved bandwidth and connection stability by reducing susceptibility to interference. In case of unexpected interference in Low Energy mode, the channel selection procedure for switching is now faster. The 5.3 protocol does not present fundamental innovations, but several qualitative improvements are evident.

— Bluetooth 5.4. Introduced in early 2023, the version increased the range and data exchange speed. Also, Bluetooth v 5.4 enhanced the BLE power-saving mode. This 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.

— Mini-Jack (3.5 mm). Standard Aux audio input for connecting speakers to an audio signal source — for example, a laptop or smartphone.

— USB. Presence of a USB port allows connecting USB flash drives, mobile phones, MP3 players, and other similar peripherals to portable speakers. Therefore, such models have a built-in player and enable using connected gadgets solely as storage devices.

— Card reader. Like the above-described USB, this feature implies the presence of a built-in player in the speaker system. A card reader allows using memory cards as storage where songs can be recorded.

— FM receiver. An integrated tuner, allowing the speaker system to function as a full-fledged FM radio receiver — this range is popular among music radio stations (particularly due to the ability to broadcast sound in stereo format).

— Mono. The simplest type of acoustics is a single-channel audio system equipped with one speaker. Of course, there is no question of any volume of sound.

— Stereo. Acoustic system equipped with two speakers responsible for the left and right channels. Allows you to create a minimal illusion of "surround" sound by simulating the displacement of the sound source in the space in front of the listener.

— 2.1. A system of two stereo speakers that create a minimal illusion of "surround" sound, and a subwoofer that provides powerful and rich sound at low and ultra-low frequencies.

The total power of all channels of the speaker system. The higher the power, the larger the size of the room in which the audio system can be used, however, more powerful portable speakers usually have larger dimensions and weight.

The range of audio frequencies reproduced by the audio system. The wider the range, the richer the sound, the more details the speakers can convey, especially in the low and high frequencies. At the same time, we note that the average human ear is able to hear sounds in the range of about 16 – 20,000 Hz, and it makes no sense to provide a wider range in speakers — a person simply will not hear it. Also note that a wide frequency range alone does not guarantee good sound quality.

Theoretically, a higher capacity allows to achieve greater battery life, but in fact, the operating time also depends on the power consumption of acoustics — and it can be very different, depending on the characteristics and design features. So this parameter is secondary, and when choosing it is worth paying attention not so much to the battery capacity, but to the directly claimed operating time (see below).

The main material used in the construction of the hull.

— Plastic. Inexpensive and at the same time very convenient material for portable acoustics. Plastic easily accepts a variety of colours and complex shapes; the latter not only gives space to designers, creating speakers of unusual design, but also allows you to apply various tricks to improve sound quality. In addition, this material is not afraid of moisture. It is believed that the strength of plastic is not very high, but this disadvantage is easily compensated by the large thickness of the material or the use of special impact-resistant grades. Therefore, plastic is found in all categories of speakers, from low-cost to high-end and from "home" to extreme, designed for an active lifestyle and frequent outdoor use.

— Metal. The metal gives the speakers a solid and expensive appearance, and on the practical side, this material is remarkable primarily for its high strength. At the same time, it is much more expensive than plastic — also due to the fact that manufacturers have to use shock-absorbing inserts and other tricks to avoid an unpleasant "metallic" coloration of the sound; and the mentioned strength is most often not critical. Therefore, metal cases are much less common than plastic cases, mainly in rather expensive portable acoustics.

— Silicone. Relatively soft and elastic mate...rial, not afraid of moisture. Suitable for creating dust, moisture and shock-proof speakers; in addition, it is convenient for models with suction cups (see above) — the part of the body that has the appropriate shape can play the role of a suction cup directly. At the same time, silicone has no other noticeable advantages over plastic, so its use is limited to specific models of portable acoustics.

— Rubber. For a number of reasons, rubber is considered well suited for models with dust and water protection, almost all speakers made of this material are protected. In addition, due to the softness of the rubber provides good shockproof properties.

— Wood. Wood is considered the optimal material for speaker cabinets in terms of acoustics. However, the specificity of portable speakers is such that this moment is not decisive in this case, and the main advantage of wooden cases over others (primarily plastic ones) is their aesthetic appearance, with characteristic colours and patterns. In addition, many consider wood a more pleasant to the touch and “natural” material. But this option does not have any special practical advantages, despite the fact that it is quite expensive. As a result, portable speakers with wooden cases are rare — they are mostly designer models created based on the original design.
