Please check the power indicator is on, if not, turn the potentiometer on. 2. If the power indicator lights, check that the VOL knob is in the smallest state, if it is, and it is normal to rotate clockwise in the minimum state. 3. If both of the above are normal, check whether the audio source playback device is paused, muted, or the volume is minimal. Q: Why the headphone has a big buzzing sound when the input line is connected but not play? A: When an unshielded signal line is empty, an interference signal will enter the amplifier and be amplified. If you dislike the sound, we suggest you replace the shielded signal line or unplug the signal line.
