About the Jabra BIZ 2300

The BIZ 2300 is a durable corded headset built for contact centers. It has an air-shock noise-cancelling microphone, a reinforced cord and a 360° spin boom arm, and weighs 65 g in the duo version.

USB versions include an in-line control unit with programmable buttons; QD versions plug into desk phones through a Jabra Link cord.

It is a lower-cost, rugged alternative to the Engage 40/50 II for agents who stay at their desks.
