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

Accsoon CoMo II master headset (Host). 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 (with 7 remotes units connected). 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. Not only: CoMo II can be integrated with a platform like Zoom by connecting the analog audio output just described to a USB audio interface on the computer (via a mini-jack > USB adapter) so that the Intercom can be recognized as a microphone source in the video conferencing software. User benefits Ultra-lightweight design weighing less than 170 g for long-lasting comfort Operating range of up to 400 meters in a straight line without interference Dual-Mic ENC and AI ENC technology with adaptive learning Reduction of hearing fatigue and discomfort caused by binaural imbalance in traditional monaural Intercom systems thanks to zero-latency sidetone Extended battery life Flip-to-Mute microphone for quick muting 3.5 mm mini-jack connector for using personal earphones Ergonomics High RF stability thanks to 1.9 GHz DECT technology Possibility of indirect integration with collaboration platforms such as Zoom via the system's analog audio output Areas of use Communication between team members during film productions Television productions and live broadcasts Concerts, theater performances, and large events Industrial and noisy environments Technical coordination in Trade shows, corporate events, and temporary installations Operational teams requiring clear and stable communications over long distances Hybrid teams combining field communication and remote collaboration
