Supporting headphones with 16-300 Ω Impedance, this amplifier offers seamless connectivity and superior sound, making it your Road Trip Essential. However, it is Not Recommended to Use while Charging to prevent noise interference.

If you find that the device is working but the music intensity is lacking, it may be due to low battery output. Take your High-Fidelity Listening Experience with you anywhere and adjust the gain switch to the "H" position if the volume is still not adequate.

While the USB on the headphone amplifier only serves as a charging function and not for OTG decoding, ensure that all cables are properly connected and check the power indicator, VOL knob, and audio source playback device if there is no audio output.

If you encounter a big buzzing sound when the input cable is connected without any audio playing, avoid using the amplifier while charging and check the connection between the audio cable and the amp interface. Additionally, if Bluetooth connection issues arise, unplug the 3.5mm audio input interface of the headphone amplifier.
