Review: Buzzy sound specially while playing an instrument. - The product is very good regarding the charging case and compact form and battery. But the sound is very bad and noisy. It is little noticable during YouTube or Spotify playback. But during recording, there is a clear buzzy sound which is there. Each stroke of guitar or similar instrument creates more buzzy fuzzy sound which is verymuch annoying. I need the form factor and there is no similar product available at this price, that why I won't return this item. The company should work on the buzzy sound.

### ⭐⭐⭐⭐⭐ Great unit for the money
*by S***F on 12 July 2025*

This is fantastic for gigging musicians. It can be plugged directly into a unit such as a hx stomp or (with the appropriate adapters) into a mixing desk or XLR on stage to the desk. I use with in ACS in-ear monitors and the sound quality is great. There is no interference like I used to get from my U Vive, which broke after about a year anyway. The fact that you charge the transmitter and receiver in the case is brilliant, as once the case is charged you can get a quick boost whenever needed. Highly recommend this!
