NU-X B7PSM 5.8 GHz Wireless In-Ear Monitoring System

The NUX B‐7PSM Personal In‐Ear Monitoring System brings professional‐grade wireless audio to performers with its cutting‐edge 5.8GHz technology and ultra‐low latency performance. This compact system automatically scans the RF environment to find clean wireless channels, providing interference‐free broadcasting with 24‐bit/40kHz high‐quality stereo audio transmission. With less than 5.5ms latency and an operational range of up to 100 feet unobstructed (32 feet when obstructed), musicians can move freely on stage while maintaining crystal‐clear audio monitoring.

The lightweight, clip‐on design makes the B‐7PSM incredibly user‐friendly, featuring a transmitter with 1/8" TRS plug and included 1/4" adaptor for versatile connectivity. The receiver clips easily to shirts, belts, or guitar straps, while the automatic frequency hopping technology ensures reliable, stable performance during live shows. The intuitive pairing system connects both units within seconds ‐ simply turn on the TX and RX, and they’ll automatically detect each other with unique pairing algorithms that prevent interference with other wireless systems including WiFi.

Each system comes complete with a custom 3000mAh charging case that doubles as a power bank for both transmitter and receiver units. The package includes everything needed to get started: the transmitter, clip‐on receiver, charging case, 3.5mm to 6.3mm stereo adaptor, and USB Type‐C charging cable. Designed for 16‐32 Ohm earphones or headphones, this license‐free 5.8GHz system is perfect for musicians, stage performers, and broadcasters seeking professional wireless monitoring without the complexity.
