14.Why does the volume of the mobile phone not change when the BTR5 adjusts the volume?
1.BTR5's own volume adjustment has a memory function, which can automatically adjust the volume.
2.We have deliberately designed the BTR5's volume adjustment to be out of sync with the mobile phone. This has the advantage of subdividing the volume level for more precise volume adjustment.What mobile phones adjust is the the volume of the Bluetooth code, too small voice will affect the dynamic. At the meantime, the BTR5 side adjusts the volume of decoding and amplification, with less loss of sound quality. So if you want to acquire better sound quality, it is recommended to adjust the volume of the phone to the maximum, and control the volume by your BTR5.
