XVive U3 Microphone Wireless System

I was so impressed when I bought my first set.
Great sound and ease of use.
Now after a few years..
Bad points
1. The button, that releases it from the microphone, has broken and I have to use electrical tape to hold it in place. Does not look very professional.
2. Annoying not being able to see the battery level.
3. I occasionally get interference and the signal pops and cuts out for a second or two. Again does not look or sound very professional. This did not happen when I first got the set. I think the 2.4ghz frequency is so busy nowadays.
Good Points
1. Very easy to use and great sound quality.
2. The mute button works without an audible 'pop'
3. When attached to a microphone, and laid on a flat surface, the set is in full connection with the surface. This alleviates any stress put on the connection to the microphone. Also the shape means it does not roll on a flat surface. This might sound trivial, but I really appreciate it.
I bought another set when the button broke so I have one as a back up.
Glad I did, as the battery has caught me out on occasion.
