I have mini m8s II 2/8Gb and FW 20170606 and everything works great !
But there is a problem with the implementation Bluetooth.
The problem is that the sound quality is terrible.
I tried to connect different Headphones, for example QCY50, Bluedio R1+
But the sound quality is bad in any case.
The profile in bluetooth is A2DP.
On stock firmware sound quality is good.
What could be the problem?
