Common Problems

Q: I have all the wires connected, but no sound output?
A:

Check whether the POWER indicator is on or not. If not, turn on the POWER knob. After rotating the power on knob, the indicator light is still not on. Check whether the battery is installed correctly and whether the battery is exhausted, or connect the charger and wait for a while to try again.
If the indicator light is on, check whether the VOL knob is in the minimum state. If it is rotated clockwise in the minimum state, it is normal.
If both of the above are normal, check whether the playback device of the input source is paused, muted, or at minimum volume.

Q: When I connect my mobile phone, can I answer the call directly when there is an incoming call?
A: Yes, on the premise that the input line must be dual 4-section and 3.5mm head, and the headset 4-section and 3.5mm with microphone function.

Q: Why is the power indicator on, but there is no sound?
A: Check whether the sound source is connected correctly, whether the player is muted/ paused, the battery is too low.

Q: Why do I plug in the input line not play the audio source, The headset will have a big buzz?
A: When the unshielded signal line is used without load, interference signals will enter the machine for amplification. If you hate the sound, it is suggested that you replace the shielded signal line or unplug the signal line.

Q: My headphones impedance is 200 Ω, can drive?
A: our machine design theory is Ω impedance headphones can promote 16-300, 200 Ω is completely no problem.
