The Plantronics S11 Telephone headset system works with your single or multi line office phone for hands-free productivity. The S11 comes with the headset and amplifier together, so everything you need to get started comes with the system.

The S11 headset is over the head and monaural, meaning that it covers just one ear. This Plantronics headset is adjustable, has a noise-cancelling microphone and a feature called Call Clarity which filters phone and room noise for clear sound without background noise.

The controls on the amplifier for the S11 are easy to use and include a volume control, a tone control and a large mute button.
