Product DescriptionThis wired headset offers plug and-play RJ9 connectivity with compatible Yealink IP phones and delivers wideband audio performance through a high signal to noise ratio speaker and passive noise cancelling microphone. Lightweight and built for all-day comfort, it features ultra light construction that weighs 10%–30% less than comparable models and includes soft ear cushions for extended wear. The boom arm rotates 330° for flexible positioning and the quick-disconnect design allows users to leave the workstation without removing the headset.
