Wireless DECT intercom system CoMo II 1 host 4 remotes - ACCSOON ACS-MIC04-1H4R

The ACCSOON CoMo II is a 1.9 GHz DECT full-duplex wireless intercom system consisting of 1 CoMo II master headset, used as the host, and 4 CoMo II remote headsets. As the evolution of CoMo, it is designed to provide clear, stable and interference-free communication even in congested RF environments. The ultra-lightweight design weighs less than 170 g, including earpads and battery, and is presented as the lightest headset in its category 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, while 1.9 GHz DECT technology provides high stability and resistance to interference. The mini-boom microphone has a Flip-to-Mute function: lifting it mutes the audio without interrupting communication.

The removable 1500 mAh battery provides up to 11 hours for the host unit with 7 remote units connected and 17 hours for each 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 and physical adjustments for different head shapes. Audio management with Sidetone uses a balanced circuit that lets users hear their own voice with zero latency while maintaining a uniform sound perception between both ears. The 3.5 mm mini-jack connector allows personal earphones to be used, improving comfort and hygiene.

CoMo II can be integrated indirectly with platforms such as Zoom by connecting the analogue audio output to a computer USB audio interface through a mini-jack > USB adapter. The intercom can then be recognised as a microphone source in video conferencing software. User benefits include a sub-170 g design for prolonged comfort, an operating range of up to 400 metres in a straight line without interference, Dual-Mic ENC and AI ENC with adaptive learning, reduced hearing fatigue and discomfort caused by binaural imbalance in traditional monaural intercom systems through zero-latency sidetone, extended battery life and fast muting with Flip-to-Mute.

The system is suitable for communication between team members during film productions, television productions and live broadcasts, concerts, theatre performances and large events, industrial and noisy environments, technical coordination at trade shows, corporate events and temporary installations, and operational teams requiring clear and stable communication over long distances.
