Portable speakers with microphone

Speakerphone

— this function allows you to use portable acoustics as an external speaker for a mobile phone. The connection to the device is usually via Bluetooth. Conversation in this mode is carried out in the same way as a regular speakerphone, however, it is often more convenient to use external acoustics for this purpose than the phone's own speaker — it usually sounds louder, and in this case the battery of the device does not run out so quickly.
