Q: Why the sound is very weak A: The sound not only depends on the volume of the microphone, but also depends on the volume of the receiver. So add the microphone volume by pressing "+" once for once (don't hold it). And also please turn up receiver volume. If there is no sound after adjusting the volume, the microphone may disconnect and please re-pair it through adjusting the transmitter and receiver to the same frequency. Easy to use.
