Output power
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.
Features
-
Speakerphone. Possibility of using portable sound system as a public address system for a mobile phone. In this mode, the sound system are connected to the device using Bluetooth, and the voice of the subscriber at the other end of the line is output not to the phone’s speaker, but through the speakers of the speaker system. This is often more convenient than holding the phone to your ear; In addition, speakerphone is useful if several people need to participate in a conversation.

NFC chip. NFC is a short-range wireless communication technology (about 10 cm). It allows for many uses, but in portable speakers it is usually used as an addition to Bluetooth, making it easier to set up the communication. For example, a smartphone with an NFC module can simply be brought close to a speaker with the same function - and both devices will automatically recognize each other, and the user will only have to confirm the communication.
-
Multipoint. A technology used in Bluetooth models that allows the speaker to connect to multiple devices simultaneously. Thanks to this, you can, for example, listen to music from a laptop, and when you receive a call on your mobile phone, switch the speakers to conversation. Different manufacturers have their own characteristics of this technology, and therefore, if the multipoint function is critical for you, it is worthwhile to
...separately clarify the details of its operation in the selected model.
- Mobile app. The ability to operate the functions and settings of portable sound system through a mobile application for a smartphone or tablet. Communication between the device and gadgets is usually carried out via the Bluetooth wireless protocol. The proprietary software may provide tools for flexible sound settings (equalizer, bass boost, etc.), managing wireless connections, selecting a sound source, etc. Also, through a mobile application, it is often possible to update the firmware of portable sound system.
— Lighting effects. Such effects can be different - from a simple set of light bulbs blinking at a constant frequency, to advanced color and music systems that produce multi-colored patterns in time with the music being played. In any case, this function has more of an entertainment meaning and does not in any way affect the sound of the device.Waterproof
The presence in the design of the acoustics of
a protected housing that prevents dust and moisture from entering the sensitive electronic filling. The specific degree of such protection in different models may be different — some speakers are able to endure even complete immersion under water (
waterproof), others are designed only for exposure to moderate rain. Therefore, the specifics of the protected case should be clarified separately according to the manufacturer's official data. However, anyway, such speakers will be more resistant to bad weather and better suited for outdoor use than those that do not have dust and water protection; therefore, if you are choosing acoustics for outdoor trips, it makes sense to pay attention to models with this function.
Some models with this feature are officially IP certified. The IP index includes two digits — for example, IP54. The first digit indicates the degree of protection against dust, the second — from moisture; the higher the number, the higher the corresponding degree of protection, detailed data can be found in special sources.
