ACCSOON CoMo II 1H2R - Host headset + 2 remote headsets of the CoMo II wireless Intercom system, digital DECT 1.9 GHz full-duplex, 400 m range

Host headset + 2 remote headsets of the CoMo II wireless Intercom system, digital DECT 1.9 GHz full-duplex, 400 m range

The Accsoon CoMo II intercom system consists of 1 × CoMo II master headset (Host) and 2 × CoMo II remote headsets (Remote).  

CoMo II is the evolution of CoMo, a headset-based 1.9 GHz DECT full-duplex wireless intercom system, designed to offer clear, stable, and interference-free communications even in congested RF environments. The new ultra-lightweight design, weighing less than 170 g (including earpads and battery), makes it the lightest headset in its category, ideal for continuous all-day use.

The system allows simultaneous communication between up to 9 users (1 host + 8 remotes) with an operating range of up to 400 meters (line of sight), guaranteed by 1.9 GHz DECT technology that ensures high stability and resistance to interference. The headset features a mini-boom microphone with a flip-to-mute function, which mutes the audio simply by lifting it, without interrupting communication.

The removable 1500 mAh battery offers up to 11 hours of battery life for the host unit (with 7 remotes connected) and 17 hours for each remote unit. The Dual-Mic ENC + AI ENC algorithm not only reduces ambient noise but also progressively learns the characteristics of the environment and the user's habits, improving the quality of the noise cancellation over time.

The ergonomic design features soft, replaceable earpads, physical adjustments to accommodate different head shapes, and advanced audio management with Sidetone, a balanced circuit that allows users to hear their own voice with zero latency while maintaining a uniform sound perception between both ears. The presence of a 3.5 mm mini-jack also allows the use of personal earphones, improving comfort and hygiene.

CoMo II also supports integration with collaboration platforms like Zoom, making it suitable not only for field productions but also for remote communication.
