Xvive U4 Digital Wireless In-Ear Monitor System

Easy, no-setup, digital wireless in-ear monitoring is here. The Xvive U4 system gives you a 90-foot range of clear audio. Just add your own 1/8" earphones!

Discover the freedom of wireless -- live, at home, or in the studio -- and roam free with your favorite earbuds, headphones, or in-ear monitors! The Xvive U4 personal wireless monitoring system is comprised of a transmitter unit, which connects to your audio source (typically a mixer or sound interface); and a belt-pack receiver, to which you connect your earphones or headphones.

Loud and Clear

The U4 system features high-resolution, 24-bit / 48 kHz audio, with a very wide and smooth frequency response between 20 Hz and 20 kHz, a signal-to-noise ratio of 107 decibels, and more volume than you'll ever need. The sound is better than CD quality, and much, much better than MP3 quality!

Long-Lasting Battery, Easy to Charge

The internal battery in both the transmitter and the receiver lasts for 5 hours. The battery is easily charged using the included USB cable and any standard 5V USB charger, and charging takes between 1.5 and 2.5 hours depending on the current of the charger being used.

Band on the Run

With Xvive U4, you can run 6 simultaneous systems with 6 separate monitor mixes, if you like. Your whole band -- up to six musicians -- can use the system together! There can be one monitor mix per transmitter, so if you have multiple U4 sets, you can customize monitor mixes for each band member. This is an easy, great-sounding and cost-effective monitoring solution for studio recording, rehearsals or live gigs. In rehearsal, this also means that there's no need for read more PA speakers -- so a band can practice in an apartment, or late at night.


The basic application is to run a monitor mix from a soundboard, wirelessly, to one set of headphones or in-ear monitors -- live, at home, or in the studio. But there's a lot more you can do with the U4 System:
- Direct Communication: If you have more than one U4 receiver, you can broadcast a signal to a whole group of people. This can be useful in situations where one person needs to communicate clearly and directly to a group -- either in noisy environments or in situations where you don't want to disturb others. This makes it an excellent option for things like group demos, presentations or tours.
- Free and Easy Recording: For recording musicians, whether in a home or professional studio, going wireless makes the whole process so much freer and easier -- especially if you're playing or singing AND engineering at the same time!
- Discreet Practice: If you want to practice guitar or bass privately -- for example, late at night -- you can run your signal through a multi-effect unit or modeling amp, send the XLR or 1/4" output to your headphones or earphones, and move freely around your home!

This review has been selected by our experts as particularly helpful.
Brought this unit into our arsenal for use with mainly guest musicians. We are an amp-less stage and have no monitors. We are completely in ear band wide. We still like to have guests on stage sometimes and this will allow us to do that for a couple songs. All we need for the guest is buds or cans. Guitarist tested it last night for entire set and loved it. Had plenty of juice to power Westone UM30 pros.

Sound quality on this unit is excellent. The frequency response is good enough to be used by a bass player. Many less expensive units can't do frequencies below 80 Hz well but this does. My only complaint on the sound is that it sounds a bit compressed. On stage I doubt you would notice. It is a MONO only system though. There is no upgrading to stereo.

Most useful feature is portability. Take this in your gig bag and hand it to the sound guy and you have an in ear system like that. Least useful is only 6 channels of 2.4 spectrum to use. If you use U2s or U3s you are sharing channel 1-4 and only have 5 and 6 to choose from.

Ease of Use
Plug them in match the channel. Done.

Metal Chassis on both units is impressive. Bulky without being lead like.

It's a bargain product. If you were going to set up your band and don't mind mono this would be a great option if you can't afford Galaxy 1400s, Shure 300, read more or Senn G4.

Manufacturer Support
I've not had the best of luck contacting them. This is my biggest reservation about XVive. I've emailed nancy@ and their marketing@ and never received answers from either.

The Wow Factor
It's cool and sounds great. It's so small!
