14. The instruction of the volume adjustment in BTR13

1. Why is the BTR13's volume adjustment is out of sync with the mobile phone's？

We have deliberately designed the BTR13's volume adjustment to be out of sync with the mobile phone's. This allows more volume levels for more precise volume adjustments, so you will no longer be worried about over large or small volume. The BTR13 supports 60 levels volume adjustment. And it has a memory volume that can automatically memorize the adjusted volume.

2. How to set the volume of the phone when connecting the BTR13 to mobile phone via Bluetooth?

What mobile phones adjust is the volume of the Bluetooth codec. If it is too small, it will affect the dynamics. While the BTR13 controls the volume of decoding and amplification, leading to less loss of sound quality. Therefore, it is suggested to set the volume of the phone to the maximum, and control the volume via the BTR13, which is convenient and can acquire better sound quality.

3. What volume adjustment settings are supported in FiiO Control APP?

You can limit the volume,adjust the Bluetooth volume and volume of call via the FiiO Control app.

The default operation mode is 'hold volume buttons to switch tracks'. You could switch to 'Double click volume buttons to switch tracks' in the FiiO Control app.

4. Is it normal the volume is lower than the mobile phone's when using the BTR13?

In fact, it is meaningless to compare the volume of the BTR13 with the mobile phone. Because the BTR13 is a graded adjustment, if the BTR13 is turned down, the volume on the mobile phone needs to be turned up. The sound resolution of the BTR13 is much better than the general mobile phone.
