It is turned to the maximum, but the volume is still not loud enough. What should I do?

This audio amplifier is designed with a gain switch,which can be set to “H” position if the sound is not loud enough.

Does Type-C have a decoding function?

Type-C of the headphone amplifier only has a charge function, does not have OTG decoding function.

All cables are connected, but there is no audio output?

1. Check the power indicator is on. 2.Check the VOL knob is in the smallest state. 3. Check whether the audio source playback device is paused, muted, or the volume is minimal.

Why the headphone has a big buzzing sound when the input cable is connected but the sound is not play?

1. It is not recommended to use it when charging, because current interference and noise may be generated during the charging process. 2.Check whether the connection between the audio cable and the amp interface is normal.

Bluetooth cannot be connected?

Please unplug the 3.5mm audio input interface of headphone amplifier.
