The Xvive U4 Wireless In-Ear Monitor System is suited to performers needing reliable cable-free stage monitoring. Designed for quick setup, this compact system lets you build a personal monitoring rig without complicated configuration. Simply connect the transmitter to your mixer or audio source, pair it with the receiver, and you’re ready to go. High-resolution 24-bit/48kHz audio and a wide 20Hz-20kHz frequency response help you hear your mix with clarity, while less than 5ms latency keeps monitoring feeling natural during live performances. The 2.4GHz wireless connection provides a working range of up to 90 feet, giving you freedom to move around the stage. With six available channels, the system can support multiple performers, and additional receivers can be set to the same channel for shared monitoring. Rechargeable batteries in both units provide up to five hours of operation, making the U4 a practical choice for rehearsals, gigs, and live events.
