Xvive Audio U4 Overview

From Manufacturer

The U4R Wireless In-Ear Monitor System from Xvive Audio provides performers and presenters a hands-free, cost-effective, and expandable solution that supplies 24-bit/48 kbps digital sound quality to their favorite in-ear and headphone monitors. This configuration includes a single receiver and a single transmitter; ready for plug-and-play use in a wide variety of settings including musical venues and and theatres, houses of worship, schools, corporate conference rooms, and more.

The portable, easy-to-use U4 system features road-worthy components housed in tough molded-plastic and cast-metal chassis built to handle the rigors of touring and designed to work with a huge variety of audio gear. The components are powered by internal non-replaceable batteries that offer 5 hours of operating time and are recharged via USB ports.

The transmitter works with basically any mixer or other device that has an available balanced XLR or unbalanced 1/4" output jack. Just plug the transmitter in, and it will broadcast the incoming audio to any of its six selectable 2.4 GHz channels. Simply set the bodypack receivers to the same channel and you're good to go. The system provides a 90' line-of-sight transmission range and a 5 ms latency, low enough for musical applications.

Xvive Audio U4 Reviews

Works flawlessly

Date: 2024-12-01

I use this in a small combo setting and it works great. It is super convenient and gives me the full mix right into my ears at a level that I can manage throughout the performance. I love it and look forward to many years of good hearing and not damaging my ears

Garbage

I ordered one, it seemed to work well, but had an intermittent headphone jack connection. So I exchanged it for another one. This 2nd one has a WORSE intermittent headphone connection, and has a horrible buzzing noise when it does work. Look elsewhere, the QA on these are non-existent.

Asked by: Christopher
Xvive recommends powering off the components of the Xvive Audio U4 Wireless In-Ear Monitor System with One Receiver while charging. The user guide states: "Please do not use U4 when charging, which may reduce battery life." Essentially, while the transmitter may be able to operate while charged, it may be detrimental to the long term battery life and performance of the unit to do so.

Will this disturb the frequencies of for example a Sennheiser G3? I'm looking to use this in location audio recording for film.
Asked by: Haand
No, the Xvive Audio U4 Wireless In-Ear Monitor System with One Receiver should not interfere with the frequency transmission of Sennheiser's EW100 G3/G4 wireless systems. The Xvive uses 2.4GHz frequencies, which are far from the UHF frequencies in the 470-608MHz range that the Sennheiser operates within.
