Spracht ZuM Maestro SPT-HS2020, Monaural, Over the Head Headset

Answer and end calls while you're away from your desk by adding a remote handset lifter or electronic hook switch. You will really appreciate the crystal clear sound and voice quality. The noise-canceling microphone screens out the noise around you so you will be heard as well as you can hear. The multi-function button allows you to answer/end calls on the headset or you can dock/undock the headset from the base station. Volume control and microphone mute can be adjusted on the headset. You can have conference calls with up to four headsets.
