Q1: Sound distortion or low volume
Maybe it's because the current is too low that the speaker's power is insufficient. Especially when connected directly to computers, the current of USB interface of some computers will be less than 1A.
Q2: Continuous noise
Because many computers don't deal with power systems in a special way, when both the audio and the power cord are connected, the speaker receives the current signal from the computer and generates noise.
Q3: Less or no bass
It may be because the speaker is underpowered, or it's because the bass diaphragm is damaged in transportation.
