The Jabra BIZ 2300 headset has an HD/broadband audio and a noise-canceling microphone. Its lightweight design will offer the user maximum comfort throughout the day. Designed to last, it is equipped withan unbreakable boom arm that swivels at 360° and the cord is reinfoced with Kevlar. The microphone has many tiny holes (instead of a single large hole) and has a foam lining on the inside. These features help to reduce the penetration of air into the microphone and thereby to improve the call quality.
