Nux B-7PRO |NUX 2.4 GHz wireless in-ear monitor system

2.4 GHz wireless in-ear monitor system, audio interface and charging dock, no headphones included

The NUX B-7 PRO is a game-changing wireless in-ear monitor system, designed for musicians who demand high-quality audio, ease of use, and total freedom on stage. With interference-free 2.4 GHz transmission, 24-bit / 48 kHz high-resolution sound, and ultra-low latency, the B-7 PRO ensures crystal-clear monitoring without dropouts. Whether you’re performing live, rehearsing, or recording, this system provides seamless wireless audio monitoring with an intuitive automatic pairing system.

A key feature of the B-7 PRO is its USB audio interface capability, allowing you to monitor and record audio directly from your computer or mobile device. This makes it ideal for musicians who want to play along with a click-track, backing tracks, or rehearse with recorded mixes. The high-definition color LCD display provides all essential information at a glance, even in dark stage environments, while the adjustable Low Latency Mode and Stable Mode offer flexibility depending on your performance setting.

After your performance, simply place the receiver (belt pack) onto the transmitter, and it will automatically charge on the go using the built-in battery of the transmitter. This means your receiver recharges while traveling to your next gig, ensuring it's ready whenever you are.
