OmniSound®
The patented OmniSound® audio technology guarantees an impressive and crystal-clear full-duplex audio in both directions. The sound is transmitted clearly and powerfully to all attendees thanks to a hypersensitive microphone with 360° audio pick-up and speakers. OmniSound® delivers HD audio in calls over IP and provider networks. It also incorporates automatic echo cancellation and noise suppression, which minimises background noise interference.

This means you can walk around in the room, talking, discussing and debating with others without loss of audio quality and without any annoying sound clipping, damping or echoes. It's as close to real sound as you can get.
