Plantronics M22 Headset Amplifier Bundle with Headset Advisor Wipe Renewed

READ BEFORE PURCHASING: Before a return contact seller for echo, static, no dial tone, hear/can't be heard is common and is resolved by quick troubleshooting! The Plantronics M22 is designed to work with your Plantronics corded office headsets. The M22 amplifier is required for telephones that don't have a designated headset port. Others choose the Plantronics M22 so you can adjust microphone and hearing volumes further that a direct connect cable wouldn't allow you to do. Lastly, you're covered with a 1 year advanced replacement warranty for peace of mind and a certified refurbished Plantronics M22 will save you around 20-30%!
