Xvive U4 Review - Are Budget IEM Systems Worth It?

I recently purchased the Xvive U4 wireless IEM system for our band's vocalist and myself as we've had generally not great experiences hearing ourselves in live situations. This kind of system isnt cheap, but its a lot more affordable than a full closed one, so I wanted to share my experience using it as I'm sure many of you may want to get into wireless monitoring but don't know if something like this would be worth it as a stopgap to a full closed IEM system.

I also had a very bad experience having on stage monitors. So I decided to do something to be able to at least hear myself and thus feel much more confident. The only solution I came up with considering my ultra tight budget was using a cheap FM radio transmitter and my phone so I could use the radio app and some earphones for IEMs.
I plug the transmitter to the phone output jack in my Cube baby pedal so I can hear the signal with a cab sim.
It's not ideal and I get some cutouts that don't last a second, but man does it feel good to finally monitor myself.
Total cost: maybe 20 bucks tops.
Good things: Price. Earphones are cheap to get and they can get some good sound isolation. The transmitter's battery life is about 2 hours, more than enough for my live shows.
Downsides: I can only monitor myself so I've gotta pay close attention to the drummer. The sound quality might not be the best. The range is not that great, so I need to stay maybe within 5-8 meters away. You also need to find a frequency that's not being used everytime you go to a different place.

I have these exact products and I agree with you 100%

The X5 System is awesome - I use them every single week in a Praise and Worship band. Battery life is great - just make sure you store them properly so they don't accidentally get switched on and run the batteries dead. I use the KZ AS10 IEMs

Yup, I tape down the power switch :D
