Lightly used; full duplex for natural, simultaneous two-way conversation, users can speak in a normal voice and be heard clearly up to ten feet away-making every call a more productive call. Smart technology, such as Dynamic Noise Reduction (DNR), provides maximum microphone sensitivity, while reducing distracting room and background noise. And the SoundStation2 offers 360-degree microphone coverage with intelligent mixing- so only the microphone closest to the speaker is on for crystal clear conferencing.
