The Jabra BIZ 2300 headset features HD / wideband audio and a noise-canceling microphone. The ultra-light design offers the user maximum comfort throughout the day. It is designed to last a long time: he has an unbreakable microphone boom swivel 360 ° and a wire reinforced with Kevlar. The aerodynamic microphone has many small holes (and not one large hole), but also a foam filling inside. These features help to reduce the ingress of air into the microphone, and thus to improve the sound quality of the calls.
