Accsoon CoMo II Full-Duplex 9-Person Wireless Intercom System

CoMo II is the evolution of the original CoMo system, offering a headset-based 1.9GHz DECT wireless intercom platform with full-duplex communication, allowing users to speak and listen at the same time without push-to-talk operation.

The system is built to deliver clear, stable, and interference-free communication even in crowded RF environments, making it suitable for filming locations, television production, live broadcasts, concerts, theater performances, trade shows, corporate events, and industrial environments.

Its new ultra-lightweight design weighs less than 170 g per headset, including earpads and battery, making it comfortable for continuous all-day use.

CoMo II enables simultaneous communication between up to 9 users. The 1 Master / Host + 8 Receiver / Remote configuration gives you a complete wireless communication setup for a 9-person crew.

The system operates on 1.9GHz DECT, a technology designed to provide high RF stability and stronger resistance to interference in crowded wireless environments, with a range of up to 400 m in direct line-of-sight conditions.

Weighing less than 170 g per headset, including earpads and battery, CoMo II is designed for users who need to wear an intercom headset for long hours during production or operation.

The ergonomic design includes soft, replaceable earpads and physical adjustments to fit different head shapes, helping reduce pressure and discomfort during extended use.

A 3.5mm mini-jack also allows users to connect personal earphones, improving comfort and hygiene when the system is shared between multiple users.

CoMo II uses Dual-Mic ENC together with an AI ENC algorithm to reduce ambient noise and improve speech clarity in noisy locations.

The AI noise reduction system progressively learns the characteristics of the environment and the user's habits, helping improve noise cancellation quality over time.

Each headset features a practical mini-boom microphone with Flip-to-Mute functionality, muting the audio simply by lifting the microphone upward.

This allows quick muting during operation without disconnecting from the system or interrupting communication with the rest of the team.

The system includes 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.

This helps reduce hearing fatigue and discomfort caused by binaural imbalance in traditional monaural intercom systems, especially during long working sessions.

Each headset uses a removable 1500mAh battery, allowing batteries to be swapped during long production days.

CoMo II can be indirectly integrated with collaboration platforms such as Zoom by connecting the analog audio output to a USB audio interface on a computer using a mini-jack to USB adapter.

With this setup, the intercom can be recognized as a microphone source in video conferencing software, helping combine field communication with remote collaboration.
