XVive U4 Langaton korvanappi monitorointi ISM 2,4 GHz

Wireless In-Ear Monitoring Freedom for Live Performance

The XVive U4 In-Ear Monitor Wireless System delivers cable-free personal monitoring for singers, instrumentalists, and bands who want to escape the limitations of stage wedges. Operating on the globally license-free 2.4 GHz ISM band, this compact digital system transmits a high-resolution 24-bit / 48 kHz signal from a bodypack-friendly transmitter to a belt-clip receiver. The XVive U4 In-Ear Monitor Wireless System is built for plug-and-play setup in clubs, rehearsal rooms, and home studios where reliable, low-latency wireless monitoring matters more than multi-channel complexity.

What Sets the U4 Apart in Its Class

Most entry-level wireless IEM systems compromise on either sound quality or latency — the U4 refuses to. Its 24-bit / 48 kHz conversion pipeline delivers a frequency response from 20 Hz to 20 kHz with a 107 dB signal-to-noise ratio, putting it well above CD-quality territory. The integrated rechargeable lithium-ion battery in both transmitter and receiver runs for 5 hours per charge and can be topped up via any 5V USB source — even while the system is in use.

Studio-Grade Conversion in a Stage-Ready Package

Audio fidelity is the U4's strongest pitch. The 24-bit / 48 kHz converter captures more detail than typical MP3 playback, and the 107 dB dynamic range gives musicians enough headroom to set a comfortable listening level without distortion.

• Bit Depth / Sample Rate: 24-bit / 48 kHz — exceeds CD quality for live monitoring
• Frequency Response: 20 Hz – 20 kHz — full range of human hearing
• Signal-to-Noise Ratio: 107 dB — clean signal floor with no audible hiss
• Total Harmonic Distortion: 0.2% — transparent signal that doesn't color the source

Reliable 2.4 GHz Wireless With Near-Invisible Latency

Wireless reliability on stage is non-negotiable. The U4's 2.4 GHz ISM band operation means no licensing fees and no interference from analog wireless microphones, while the 5 ms latency sits below the threshold most performers can perceive.

• Wireless Band: 2.4 GHz ISM worldwide open band — license-free in most countries
• Latency: 5 ms — effectively real-time for live performance
• Operating Range: 27.5 m / 90 ft line-of-sight — covers small-to-mid venues
• Channels: 6 switchable / 6 simultaneous — supports up to six band members on independent mixes

Compact Bodypacks, XLR Input, and USB Charging

Hardware design focuses on portability. The transmitter weighs just 90 g and plugs into any XLR output (a 6.35 mm TS adapter is included), while the 118 g receiver clips to a belt or guitar strap and feeds any headphone or IEM via its 3.5 mm jack.

• Transmitter Input: XLR (with 1/4" TS adapter) — connects to mixer aux sends or stage snake returns
• Receiver Output: 3.5 mm stereo jack — works with any standard IEM or headphone
• Battery Life: 5 hours — covers a full club set or rehearsal block
• Charging: 5V USB, 2.5 hrs full charge, usable while in use
