It connects well, the battery for calls lasts for several conversations. I use it to play music via Bluetooth from my phone in the car. It is important that it does not produce static in the speakers and does not lose its connection. For this type of use, the battery lasts a solid 4 hours.

The only negative thing about it is that when you speak on a call with the mobile connected, the other person cannot hear you well, maybe the microphone has low sensitivity.
