The NUX C-7 Stereo Wireless In-Ear Monitor System turns your favourite wired earphones into a high-performance wireless monitoring rig.
Operating on the clean 5.8GHz frequency band, it bypasses the crowded 2.4GHz spectrum to give performing musicians, livestreamers, and rehearsing bands a rock-solid audio link with negligible 7.5ms latency.
If you are looking to cut stage clutter without sacrificing monitoring quality, the C-7 delivers a flexible, professional wireless setup in a compact package.
High-Stability 5.8GHz Transmission
By utilising the 5.8GHz ISM frequency band, the C-7 avoids the congestion common to standard Wi-Fi and Bluetooth gear. It maintains a clean, interference-free connection with an operating range of up to 30 metres. Dynamic range reaches 96 dB with under 0.4% total harmonic distortion at 1 kHz, delivering transparent, high-fidelity audio directly to your ears.
Intelligent Display and Tailored EQ
Both the transmitter and receiver feature an integrated display screen, giving you instant visual feedback on active channel selection, remaining battery life, and overall system status. For precise sound tailoring, the C-7 includes 5 preset EQ options alongside selectable stereo and mono operating modes, allowing you to quickly adapt the mix to suit live stages, practice rooms, or broadcast streaming.
Dedicated Charging Case and Extended Battery Life
The included 3000mAh charging case keeps the transmitter and receiver organized while providing active portable power. A single button press starts the charging cycle inside the case, which holds enough reserve to recharge the system twice. Combining the 6-hour continuous runtime from the internal batteries with the charging case yields over 18 hours of total operational time on the go.
Flexible Band Monitoring and Multi-Receiver Support
Featuring both Auto and Manual pairing modes, the C-7 system easily pairs one transmitter with multiple receivers. This makes it a cost-effective solution for whole-band synchronized monitoring, allowing every member to receive the same clear stereo cue without running extra cables or dedicated transmitters.
