12. What's the bluetooth version of BTR3? Why isn't it the bluetooth 5.0?
A: BTR3 uses the bluetooth 4.2. Actually the Bluetooth 5.0 may not help with the sound quality too much compared with the bluetooth 4.2. Moreover, some bluetooth codecs like LDHC still hasn't adapted to the bluetooth 5.0, we decided to use the mature bluetooth 4.2 version for BTR3.
