Xvive U4 Wireless in-Ear Monitor System Professional IEM System Transmitter and Beltpack Receiver for Studio, Band Rehearsal,Live Performance (U4)

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 Amazon.m4v

Charges fast, easy setup, works well!

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.

I’ve been using this wireless guitar system for rehearsals and live performances, and it has worked really well. The connection is stable, the sound quality is clear, and the setup only takes a few seconds. It gives me the freedom to move around without worrying about cables. The battery life is good, and the transmitter and receiver feel solid and lightweight. The only reason I’m giving it 4 stars instead of 5 is that the range could be a little better in crowded environments, but for most situations it performs very well. Overall, it’s a great value for the price and a reliable choice for any guitarist looking to go wireless.

Very nice quality sound. Bass sounds nice. Tried other cheap brands and the bass was never as clear like these.

Dollar for dollar and pound for pound, you WILL NOT find a better in-ear system than what you're looking at right now. I've used virtually every brand on the market and, for the money, these are miles ahead of the competition. The have a reasonably flat response (where many are bass-boosted thinking that everyone wants to just hear the thump). But not here... these are much more balanced and offer the whole range of sound in your ears to provide a quality, flat response, with good volume control on the belt and interference-free connectivity with the base unit. It's exactly what you're looking for as a musician... you want to hear EVERYTHING. Including the click. And, this is your best route to go. Well made. Well designed and thought out. And sounds great. All at an unbelievable price!!!

I have had this U4 set for about 6 years now and is used every week for worship services. It lasts through practice and 2 services without a problem and still has enough charge to last for another practice or service. If you're looking for an excellent wireless option, I recommend it. Works great in a Behringer P16 Mixer.

This device was a life saver. We have two sign language interpreters who struggle swapping the one receiver we had. With two receivers they only need to go on the spot. The one transmitter we have broadcast to both receivers. PERFECTO!!!!

Fonctionne très bien et très impressionnant

Only potential negative is that it is 2.4GHz, which can be more prone to interference. I do not undertsand why they include an unbalanced rather than a balanced XLR -> 1/4" adapter.... ¯\_(ツ)_/¯

Great. Just didn’t work for my system
