Accsoon CoMo 2 Intercom Introduced – 170g, AI Noise Cancellation, Up to 9 Users

At NAB 2026, Accsoon pulled the cover off the CoMo 2, a second-generation 1.9GHz DECT full-duplex wireless intercom. The new headsets are significantly lighter, add AI-assisted noise cancellation on top of the existing dual-mic ENC, and scale to nine users without a base station, with availability targeted for May.

We caught up with Effy Ding from Accsoon on the show floor to find out what has changed since the original CoMo, which we covered when it debuted at NAB 2024, and the 2.4GHz CoMo SE that followed at IBC 2024. The short version: the core DECT platform and 400m (1,312ft) line-of-sight range carry over, but almost everything around them, from the form factor to the audio processing pipeline and the battery release, has been reworked.

A much lighter, more comfortable form factor

The most immediately obvious change is weight. According to Accsoon’s published specs, a single CoMo 2 headset tips the scales at under 170g (6oz) with the ear cushion and battery installed, and the host unit measures 182×170×78mm (7.16×6.69×3.07in). Effy pointed out that side by side with the original CoMo, the difference in mass and bulk is very apparent, which matters more than it sounds when you are wearing a headset for a full shoot day and the weight starts to pull on your neck.

Accsoon has also redesigned the battery attachment. The original CoMo used a clutch-style system that, based on user feedback, was a little too easy to dislodge in the field. The CoMo 2 replaces it with a push-button release, so the battery stays locked in until you specifically want to swap it. Effy explained that this was a direct response to complaints from owner-operators and rental houses that wanted a more rugged, long-term dependable mechanism.

On the connectivity side, each headset now has a 3.5mm headphone jack, which lets users plug in their own single-ear or dual-ear headphones instead of being tied to the built-in earcup. A USB-C port is also present, but Effy confirmed it is reserved for firmware updates, not audio or charging passthrough.

AI noise cancellation joins dual-mic ENC

The original CoMo already used dual-microphone Environmental Noise Cancellation (ENC) to separate speech from ambient noise. The CoMo 2 keeps that and adds a second processing layer Accsoon calls AI ENC (or AINC). According to Effy, the AI layer is designed to continuously learn the acoustic profile of the environment the headset is in, so the more time you spend in a given soundscape, the better the noise cancellation should adapt.

Accsoon’s own spec sheet confirms both modes are on board, with a 16kHz/16-bit sampling rate, a frequency response of 150Hz to 7kHz, and a signal-to-noise ratio greater than 65dB. That frequency range is deliberately tuned for speech intelligibility rather than music reproduction, which is the right call for an intercom headset.

Range, stability, and through-wall performance

The CoMo 2 stays on the same 1.9GHz DECT spectrum as the original CoMo, with GFSK modulation. In our recent guide on how to choose a wireless intercom system, we explained why this band tends to outperform 2.4GHz on busy sets where Wi-Fi, video transmission, and wireless follow-focus systems are all competing for airspace.

Line-of-sight range is unchanged at 400m (1,312ft). What Accsoon says is new is the through-wall behavior. Effy told us that with the redesigned RF path, the system maintains a usable connection in environments with multiple obstructions, and that in their internal testing they were able to run a reliable link between someone on the first floor of a building and someone on the sixth. That figure is Accsoon’s own claim and clearly depends on the composition of the walls in question, so we will be curious to see how it holds up in typical concrete stage environments.

Battery life and charging

Each CoMo 2 headset charges from flat in around two hours. Effy quoted runtimes of up to 10 hours for the host headset on a single battery and up to 17 hours for a remote headset. As is always the case with wireless intercom, the master or host unit works harder than the remotes because it is managing the group, so planning spare batteries around the host is the sensible approach.

Batteries can be charged externally and are swappable in the field, which is in line with how the original CoMo and CoMo SE were packaged.

Scaling to nine users, kits, and ecosystem

The CoMo 2 is headset-based and does not require a hub or belt pack. One unit is configured as the host and the other units link to it as remotes, with a maximum of one host plus eight remotes, or nine total users, on a single group. This is the same ceiling as the original CoMo.

Kit configurations will mirror the first-generation lineup: single host, single remote, 1+2, 1+4, 1+6, and 1+8 bundles. One thing existing owners should know: Effy confirmed that the CoMo 2 is not backwards compatible with CoMo 1 headsets. The two generations cannot be mixed in the same group, so upgrading means committing to the new ecosystem rather than extending an existing kit.

On the question of expanding beyond nine users, Effy told us a hub-based or hopping solution is on Accsoon’s roadmap, though no release window has been communicated yet. For now, productions that need more than nine positions will need to split into multiple groups or look at broadcast-tier systems from the likes of Clear-Com or Riedel.

Price and availability

Accsoon is targeting general availability for mid-May, with pricing yet to be announced at the time of the interview. Given that the original CoMo launched at $299 per headset and the budget-oriented CoMo SE sits at $99 per headset, we would expect the CoMo 2 to slot somewhere in or above the original CoMo’s pricing tier, but we will hold off on any firm prediction until Accsoon publishes official figures.

Are you currently using a wireless intercom on your shoots, and would a lighter form factor with AI-assisted noise cancellation be enough to move you to a new system? Don’t hesitate to let us know in the comments below!
