Xvive U45 IEM wireless system

The Xvive U45 In-Ear Monitor Wireless System
The U45 system comprises a transmitter that connects to an audio source and a belt-pack receiver for earphones, headphones, or in-ear monitors. It delivers high-resolution, 24-bit/48kHz audio with a wide, smooth frequency response, operating on the less-crowded 5.8GHz ISM band for reliable, interference-resistant performance.

Built for Real-World Monitoring
Typical applications include monitor mixing, group communication, recording, private practice, and band monitoring, with up to six simultaneous systems supported in one venue — making the U45 just as useful for a full band's in-ear setup as it is for a single musician practicing at home.
Reliable, Low-Latency Performance
Operating on the 5.8GHz band keeps the U45 clear of the interference that plagues busier frequencies, while just 5ms of latency and a 110dB signal-to-noise ratio mean what you hear in your ears matches what's actually happening in real time. A wide 20Hz–20kHz frequency response and 0.2% total harmonic distortion keep the sound faithful across the full range, whether you're monitoring a click track or a full mix.
All-Day Battery, Ready When You Are
The rechargeable battery runs up to 5 hours per charge and recharges via USB in as little as 1.5–2.5 hours — and stays usable while charging, so you're never fully sidelined between sets. At just 90g for the transmitter and 118g for the receiver, the U45 stays out of the way whether it's clipped to a belt or tucked into a pocket.
Why We Love This
Our Gear Experts reach for the U45 when they need reliable in-ear monitoring without being tethered to a snake or monitor mixer. The 5.8GHz band means fewer dropouts in busy venues, while support for up to six simultaneous systems makes it just as viable for a full band as a solo practice session. Combined with genuinely low latency, it's a wireless IEM solution that doesn't ask you to compromise on feel.
