The Yealink CPE90 is a Wired Expansion Microphone which works as an audio input device for the Yealink Android IP Conference Phone (CP960). Up to two expansion microphones can be connected to a Yealink Android IP Conference Phone (CP960), which extends the range by an additional 3 meters / 360° respectively. Advanced echo cancellation and noise suppression filter out unwanted sound, so all that remains is crystal-clear voice. The CPE90 is a clear-cut choice for organisations which enables optimal microphone placement and room coverage.
