FAQ:
Q: What should I do if I feel electric noise?
A: There are three ways to tackle this problem. 1. Normally, it's just the noise level, generally you can't hear it at 100cm. Don't mind. 2. You can replace input signal source or replace audio signal cable with shielding and anti-interference. 3. Replace power supply or add a power supply filter.
