The AC is humming. Someone's keyboard is clacking three desks over. The far-end participant hears an echo that makes the whole call feel like a bad speakerphone. Your current mic picks up everything in the room and none of it clearly. The Yealink CM20 sits low on your ceiling at 83mm, uses 16 omnidirectional units to beamform exactly where the voices are, and its AI Dynamic Noise Reduction plus AI Reverberation Suppression sort out the rest automatically. No separate DSP box needed – it's built in and plug-and-play with Yealink MVC systems. Your next call sounds like a studio, not a school canteen. In stock in Australia
