Developed with Environmental Noise Cancellation (ENC), as well as Acoustic Echo Cancellation (AEC), the speakerphone blocks any external noise and removes echoes, reverb, and unwanted added sounds to provide a better audio experience than your laptop alone. It boasts an omni-directional, 6-microphone array and picks up audio from up to 16 ft./5 m. away ensuring you and your collaborators are heard clearly, while its wide-band speaker delivers crisp, quality sound whether you're listening to your colleagues or your favorite focus tunes.
