Independent shopping perspective
The Korena take
NUX’s B-7PSM is a compact personal wireless in-ear monitoring system for performers who need a body-worn receiver. It scans the RF environment, finds a clean channel, and assigns it automatically. Stereo audio is transmitted at 24-bit/40kHz with latency below 5.5ms. The receiver clips to a shirt, belt, or guitar strap, keeping it close during a set. Its range reaches 100 feet outdoors without obstructions, dropping to around 33 feet outdoors when obstructions are present; a charging case is included.
Strong match
Who this is for
- Stage performances needing a clipped receiver on a shirt, belt, or guitar strap.
- Outdoor performance setups with a clear, unobstructed path between transmitter and receiver.
Consider the trade-offs
When to look elsewhere
- Outdoor receiver placements beyond approximately 33 feet when obstructions separate it from the transmitter.
- Use periods longer than its stated four-hour battery running time without recharging.
