Headset intercom master DECT CoMo II host - ACCSOON ACS-MIC04-H

ACCSOON ACS-MIC04-H is the master headset (Host) for the CoMo II full-duplex wireless DECT intercom system, the evolution of CoMo based on 1.9 GHz DECT technology. It is designed for clear, stable and interference-free communication even in congested RF environments. The ultra-lightweight design weighs less than 170 g, including earpads and battery, making it suitable for continuous all-day use. The system supports simultaneous communication between up to 9 users: 1 host and 8 remote units. Its operating range reaches up to 400 metres in a straight line without interference.

The mini-boom microphone includes Flip-to-Mute: lifting the microphone mutes the audio quickly without interrupting communication. The removable 1500 mAh battery provides up to 11 hours of operation with 7 remote units connected and up to 17 hours with 1 remote unit. The Dual-Mic ENC + AI ENC algorithm reduces ambient noise, progressively learns the characteristics of the environment and the user's habits, and improves noise cancellation over time.

Ergonomic features include soft, replaceable earpads, physical adjustments for different head shapes and Sidetone audio management. The balanced circuit lets users hear their own voice with zero latency while maintaining an even perception of sound between both ears. This reduces hearing fatigue and discomfort caused by binaural imbalance in traditional monaural intercom systems. The 3.5 mm mini-jack allows personal earphones to be used, improving comfort and hygiene.

CoMo II can also be integrated indirectly with collaboration platforms such as Zoom. Connect the analogue audio output to a computer USB audio interface through a mini-jack > USB adapter, allowing the intercom to be recognised as a microphone source in video conferencing software. The 1.9 GHz DECT technology provides high RF stability. Applications include communication between team members during film productions, television productions and live broadcasts, concerts, theatre performances, large events, industrial and noisy environments, trade shows, corporate events and temporary installations. It also supports technical coordination and hybrid teams combining field communication with remote collaboration.
