Abstract
Disclosed are methods and devices for communicating between a user device, such as a mobile terminal, and a three wire headset assembly having two microphones coupled thereto. The methods provide two microphone uplink communication and stereo audio playback on a three wire headset assembly without requiring a fourth wire or the addition of a separate voice processor. The headset assembly includes a primary microphone and secondary microphone spaced some distance apart for applying techniques of noise reduction and suppression. The headset assembly includes two speakers. Controlled switches are also included in both the user device and headset assembly to achieve dual use for a single wire of the three wires. The three wire headset may advantageously support both stereo playback and two microphone voice processing. In some embodiments, two microphone noise suppression for a wired headset mode of the user device is provided.
