XVive U4 Monitor Wireless System

It looks pretty sturdy and, but I had to send it back 4 times.
The first problem was the XLR/Instrument connector. The "Click" part wasn't clicking in, so the sound came out way too low.
BTW, you need some strength to attach the adapter to the transmitter.

When I got a new one, it worked for a while but the lows were having a hissed/noise sound. Sent it back. I got the same one back because they couldn't find the issue.

This last one gets interferences (due to the 2.4GHz) that I can't use a wireless system on my Bass anymore.
If you play in tiny bars or are annoyed by cables, that can be the one to go, but not for big stages.

I bought this because it was portable, simple and easy. It connects effortlessly, you can switch between 6 frequencies and battery life was quite good, got me through a 3 hour gig.

Since it's only mono it leaves much to desire. I used it with a cover band in a mid size venue and while the XVive did it's job, I definitely need my IEM to be stereo. As a vocalist and a professional, this didn't fit me. I didn't love it - but I didn't hate it though.

If you're just getting into IEMs and want to try something without spending too much money, this is an OK option.
