Review: GREAT IEM WITH A SMALL FOOTPRINT!! - I created an unboxing video for this item to show just how small and handy it really is! I used it for the next Worship Team set on a Sunday and it did not disappoint!! We rehearsed for 3 hours with music and vocals. The batteries in this thing were strong the entire time. No dropouts, or fading of sound. U4 performed flawlessly. There was no interference from the many other wireless systems in use! I used IEM headphones that plugged right into the receiver and clipped the receiver to my pocket. As expected, the clip held fast and the receiver did not move or slip during the performance. The transmitter was used with the adapter, and it too performed flawlessly. Again, no interference and no dropouts. It was quick to plug in, and while the footprint with the adapter was a bit on the long side...it still didn't get in the way. On a soundboard, it would not need the adapter, so the footprint would be that much less. This was a very simple setup. it was truly "plug and play". The build quality is amazing. Buttons, slides and lights are all tight and sturdy. I would say that this unit will last for years. The price for this unit was far better than any other IEMs I've seen, and much much smaller...yet...it delivers a beautifully crisp, quiet audio experience. It has a gain control which is nice and comes with a LINE/AUX switch, and 8 channels to select from in the unlikely event you do get some interference. This unit operates on the 2.4 ghz frequency which is very quiet. It is a MONO only unit. In short...the unit is extremely well made, performs flawlessly and provides a true "plug and play" experience. Xvive Unboxing for desertcart.m4v

### ⭐⭐⭐⭐⭐ Great IEM wireless system
*by D***W on October 30, 2023*

I've been looking for a wireless IEM system for a long time. Most of the less expensive ones are really cheap looking and the ratings are not particularly overwhelming. Looking online I see that the XVive U4 gets high marks not only on Amazon, but from industry leaders as well. I decided to just go with the bit of extra money and get one. It is well made from metal and plastic and has a nice weight to it. I've used it 4 times now and have 2 other band members who have purchased the system based on how happy I am using it. It works great plugging straight into our Soundboard board or plugging it into the Behringer P16 personal mixer. I also use it at church to monitor the sound output of the board we use. I'm very pleased with the ease of use, quick set up, battery life and size of this awesome wireless IEM system.
