NUX B-7PSM 5.8GHz Wireless In-Ear Monitoring System | Personal IEM with Charging Case
The NUX B-7PSM is a personal wireless in-ear monitoring system (IEM) designed for modern musicians and performers. It utilizes advanced 5.8GHz wireless transmission technology to effectively avoid the congested and interference-prone 2.4GHz Wi-Fi and Bluetooth bands, ensuring stable, interference-free audio transmission in any performance environment. With automatic frequency scanning and pairing, it's ready to use right out of the box without complicated setup.
This system delivers 24-bit / 40kHz high-resolution audio quality with a wide dynamic range and clear stereo performance. Ultra-low latency (< 5.5ms) ensures that you feel virtually no delay while playing, maintaining perfect rhythm. The lightweight transmitter and receiver design, coupled with the included 3000mAh charging case, provides over 12 hours of total battery life, making it the perfect companion for touring, rehearsals, and personal practice.
Core Advantages & Applications
Interference-Free 5.8GHz Band
Most home and stage equipment crowd the 2.4GHz band, leading to signal dropouts. The B-7PSM operates on the less congested 5.8GHz band, providing a cleaner transmission channel to ensure your monitoring signal is always stable and reliable, with a range of up to 30 meters (line-of-sight).
Professional Stereo Sound
Supports Stereo transmission, perfect not only for mono monitoring but also for faithfully reproducing the stereo field of keyboards, electronic drums, or mixed tracks, giving musicians a more spacious and layered mix in their ears.
Portable Charging Solution
The receiver (RX) and transmitter (TX) provide approximately 4 hours of continuous use per charge. The included dedicated charging case protects the devices and can fully recharge the system 2-3 times, freeing you from battery anxiety during long sessions.
