Review: Works great - better quality than my Shure - I read all the bad reviews and bought them thinking I would possibly be sending them back but what a surprise - they are outstandingly good. The only problem I can foresee is the fairly short charge - I will have to remember to turn them off between sets or I may even buy another so I can use and charge all night long. (I do a total of 1 3/4 hours on stage playing but I am there for up to 4 hours) but well worth it for the excellent sound quality.
Review: Great unit for the money - 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!

### ⭐⭐⭐⭐⭐ Great unit for the money

### ⭐ Distortion not acceptable
*by A***R on 3 September 2024*

Had to send back as the distorted signal was pretty bad. It does become less noticeable at louder volume but anything less than full stage volume it's noticeable. I find it hard to believe that this would be anything other than a design fault.
