Glossary
Bluetooth
The presence of a Bluetooth module in the amplifier for direct wireless communication with other devices - primarily with audio sources that also support this technology (for example, a smartphone, tablet or laptop).
The main convenience of Bluetooth amplifiers is, first of all, the absence of additional wires, which can create various inconveniences. At the same time, the range of wireless communication is usually at least several meters. On the other hand, during normal transmission via Bluetooth, the digital audio signal is heavily compressed, which worsens the sound quality. To correct the situation, Bluetooth models may include aptX technology, which increases the purity of the signal almost to the level of wired Audio CD (or even Hi-Res Audio - in the aptX HD version); however, such functionality significantly affects the cost, and sophisticated music lovers often easily notice the difference between aptX and a wired connection.
In light of all the above, Bluetooth does not make sense to install in stationary equipment, so nowadays such modules are used only in portable amplifiers (see "Type"). At the same time, some of these models are positioned not so much as amplifiers, but as Bluetooth adapters for wired headphones. Nevertheless, such a solution can be a good alternative to classic wireless headphones: decent wired "ears" in combination with a Bluetooth amplifier can provide higher sound quality at a comparable,...or even lower cost, and often such a set turns out to be even more "long-playing" in terms of work without recharging.

Mobile app
Presence of a program to enhance the quality and volume of sound when listening through headphones. Mobile applications allow you to increase volume, adjust the equalizer, boost bass, add surround sound effects, and customize sound to individual preferences.
