NUX B-7PSM Wireless In-Ear Monitor — 5.8 GHz Stereo IEM System

The NUX B-7PSM is a wireless personal in-ear monitor system built for performing musicians who need cable-free stage monitoring. Operating on the 5.8 GHz frequency band, it sidesteps the congested 2.4 GHz spectrum used by Wi-Fi and Bluetooth gear. The system pairs automatically when switched on, scanning the RF environment for a clear channel. Stereo audio broadcasts at 24-bit / 40 kHz with latency below 5.5 ms.

Auto-Scanning 5.8 GHz Transmission and Instant Pairing

Built around an automatic RF environment scan and frequency-hopping algorithm, this model holds a clean wireless channel even when several systems run side by side. Each TX/RX pair uses a unique pairing algorithm so signals never collide with local Wi-Fi. The rechargeable storage case tops up both units via USB-C and can recharge the system roughly three times.

Audio Performance and Signal Quality

Audio quality on this instrument is shaped by the 24-bit / 40 kHz stereo engine and a 92 dB dynamic range. Frequency response spans 20 Hz to 19 kHz, and total harmonic distortion stays under 0.6% at 1 kHz.

• The 24-bit / 40 kHz sampling rate offers broadcast-grade stereo resolution for clear monitoring.
• Frequency Response: 20 Hz – 19 kHz — full-range coverage for vocals and instruments
• Dynamic Range: 92 dB — headroom for loud stage mixes

Wireless Range and Latency

The 5.8 GHz digital link holds a stable connection at up to 100 ft / 30 m line-of-sight, dropping to roughly 33 ft / 10 m when obstructed. End-to-end latency stays under 5.5 ms, and transmission power sits below 25 mW EIRP.

• Operating in the 5.8 GHz band helps to avoid crowded 2.4 GHz Wi-Fi and Bluetooth traffic.
• Operating Range: 30 m line-of-sight / 10 m obstructed — covers small-to-mid venues
• Latency: < 5.5 ms — tight enough for live performance timing

Hardware, Battery, and Connectivity

The transmitter ships with a 1/8" TRS plug plus a 1/4" adapter, dropping straight into a mixer headphone output. The receiver's clip design locks onto a shirt, belt, or guitar strap. The 3.7 V / 450 mAh battery delivers over 4 hours per charge, and the storage case adds roughly 15 hours of total runtime.

• TX Connector: 1/8" TRS with 1/4" adapter — fits most live and personal mixers
• RX Output Power: 57 mW RMS @ 16 Ω — drives 16–32 Ω in-ear buds cleanly
• Battery Life: > 4 hours per charge — covers a typical set
• Case Runtime: ~15 hours / ~3 top-ups — multi-gig day coverage
