Compact wireless monitoring

The XVive U4 Monitor Wireless System is a digital wireless in-ear system for monitoring applications. It operates in the 2.4GHz ISM radio band and can therefore be used without registration and free of charge worldwide. This wireless solution has an ultra-compact design and comprises a receiver weighing just 118g as well as an even lighter 90g transmitter. The latter measures just 10cm in length and requires only very little space on the outputs of monitor mixers, audio interfaces, and other devices. Despite its small size, however, the wireless monitoring system excels with a detailed sound thanks to its high-quality 24-bit/48kHz conversion and a dynamic range of 107dB. It also leaves nothing to be desired in terms of frequency by fully covering the normal human hearing range (from 20Hz to 20kHz).

Low latency and quick charging

The transmitter of the XVive U4 Monitor Wireless System can be plugged into an XLR socket, and the scope of delivery also includes an adapter for connecting to 6.35mm jack sockets. The receiver in turn features an output socket in 3.5mm mini-jack format. This digital system’s low latency of just 5ms can be ignored in practical applications, and musicians can expect a sound with minimal distortion thanks to a THD value of only 0.2%. The transmitter and the receiver both feature in-built rechargeable lithium-ion batteries that can be fully charged within 2.5 hours and subsequently provide power for an operating period of up to five hours. PCs, power banks, or AC adapters can be used to charge the batteries with the required 5V via a USB cable, and charging is even possible during operation.

The XVive U4 Monitor Wireless System offers beginners and advanced amateur musicians a digital wireless monitor solution that can be set up with minimal effort thanks to its plug-and-play design and, at the same time, scores points with its comparably high sound quality. This compact wireless solution is ideal for all users who are satisfied with a range of up to 27.5m and a mono signal, and it is also an excellent choice for those who want to use several wireless units simultaneously, as the six radio channels provided can be operated in parallel, allowing up to six wireless devices to be used at the same time.

About XVive Audio

Xvive Audio officially entered the market in 2012 with its compact U2 wireless guitar system. Since then, the company has also been involved in the development of wireless microphone technology. Its catalogue also includes effects pedals, such as the Signature Series, which were developed in partnership with guitarist Thomas Blug. The products are designed by an American team, based in Pasadena, California, which is composed of musicians and engineers and draws on decades of professional experience. Its lead designer, Howard Davies, was previously employed at Electro Harmonix and Pigtronix, among others. Xvive Audio's goal is to create products that deliver exceptional sound and build quality, while remaining affordable for any musician.

Up to six systems at once

Bands with up to six musicians in the lineup can use the XVive U4 Monitor Wireless System to wirelessly transmit their monitoring signals to every member while playing, and those who use their own monitoring system in both the rehearsal room and on stage can develop an optimum wireless monitor sound. Singers and speakers can easily wear the compact bodypack, which is just 6cm tall, on their belt, and the clip mechanism also allows it to be securely attached to the strap of an electric guitar or bass. Guitarists can of course use the XVive U4 Monitor Wireless System at home to move around freely in the room while practising their licks and riffs.

Good product idea, bad execution
dan16 08.11.2021
So we actually bought 3 of these sets for our church. They seemed to be a cheaper alternative to the regular wireless in-ear systems. The first one came with a defect from the factory on the connector. We returned it and received another one that worked well.
For the first few months they worked well but then one of the senders started to randomly select the channel by itself and although the channels were very rarely changed, the button to change the channel stopped working. You could not press it anymore. We returned it and it was fixed. A month later the 3rd set starting to show the same behavior with the channel button. It is very frustrating to not be able to rely on them. As a summary:
- Great concept, works on 2.4 GHz so no interference from other microphones
- Good price

- Button to switch the channel is very badly built
- Only mono, which makes creating a good in-ear mix very difficult.

This was my first foray into the world of wireless transcievers.

It allows great freedom when performing.

The physical design of the receiver is perfect. You can clip it on your waist and ride the volume knob with out need to look for it.

Audio quality is excellent. There's a great range over which this device transmits audio.

If you're looking for a wireless transceiver kit, this is one of those "zero regret" buys.

Using 4 receivers on 4 transmitters is no problem. But when you switch on your Line6 G90 Wireless Rack system the U4 units will drop out but also the G90 systems drop out every few seconds.
Not compatible!


Xvive the company are extremely poor to deal with
Owen K. 05.02.2023
A large sticker on the front of the X-Vive states you can register with them for a 4 year warranty extension. I did so, but there's 2 stickers on the box. I used an incorrect S/N label which appears to be Thomann's own, and XVive's website stated that they had received the registration. I thought, all good, I'll bin the box. Then a few days later I got a rejection email.

It's taken me until now, 3 months from original purchase to find the box. I went to register again with the second serial number and Xvive rejected it because it's out of the 45 day period. I explained the circumstances, and received a cold rejection - no token of goodwill, no exception made for a genuine customer.

I won't be buying an Xvive product again. And our Drummer's U4 pack had a switch failure and had to be returned. Shocking company, shocking quality. Avoid.
