Accsoon CoMo II long-range full-duplex DECT wireless intercom system

Accsoon has officially announced the Accsoon CoMo II, a long-range full-duplex DECT wireless intercom system designed to provide reliable real-time communication for film crews, live production teams, etc.

We first saw the Accsoon CoMo II at NAB 2026.

The 1.9GHz full-duplex wireless intercom system offers a claimed operating range of up to 1312ft (400m). Powered by Accsoon’s proprietary wireless stability technology, the Accsoon CoMo II is said to deliver reliable signal penetration and stable multi-user communication, even in environments with obstacles or challenging signal conditions.

The headsets have been completely redesigned, and they are a lot lighter and more comfortable to wear than their predecessors. The adjustable structural design allows the headset to adapt to different head shapes, helping maintain a secure and comfortable fit.

With a battery inside, the headsets only weigh 170g (including battery and earpads). As a comparison, the previous CoMo weighed 257g.

Building on Accsoon’s wireless technologies, the Accsoon CoMo II eliminates the need for traditional base-station systems while delivering stable long-distance communication and extended battery performance. The Master headset provides up to 10 hours of operating time, while each Remote headset delivers up to 17 hours of battery life.

The Accsoon CoMo II incorporates dual-microphone ENC (Environmental Noise Cancellation) together with AI-powered noise reduction, helping isolate speech from heavy background noise commonly encountered on set.

• 

Using an adaptive AI system, the intercom is claimed to continuously learn from real-world environments and then suppresses unwanted noise while preserving voice clarity. This enables production teams to maintain clear communication even in noisy environments.

The Accsoon CoMo II is enhanced for voice communication, with a 150Hz–7kHz frequency response.

The system supports full-duplex communication, allowing all connected users to speak and listen simultaneously without push-to-talk operation.

A single Master headset acts as the communication hub, connecting directly with up to 8 Remote headsets, supporting teams of varying sizes:

• 1 Master + 2 Remote – 3 users
• 1 Master + 4 Remote – 5 users
• 1 Master + 6 Remote – 7 users
• 1 Master + 8 Remote – 9 users

This versatile configuration allows the system to scale depending on crew size and production requirements.

The CoMo II also offers support for external 3.5mm headsets, enabling users to connect their preferred earphones.

Please note that when using an external microphone, the boom mic cannot be muted by flipping it upward; the built-in microphone and speaker are automatically disabled, and Dual-mic ENC is not available.
