Who we are logo, BTP representative with headsets

Every order includes unlimited lifetime support from our Headset Helpdesk, saving you time and money.

Plantronics S11 Hands-free Convenience for the Home Office

  • Manufacture Discontinued March 2021 – Replaced EncorePro 310 QD with Vista M22
  • Does not have a quick disconnect (QD) – must take headset off when you leave your desk
  • We recommend commercial grade products (such as Plantronics H series tops combined with the M22 amplifier) because they have a quick disconnect, optimal hearing protection, a 2 year warranty and all around better performance
  • This product is consumer grade; not built for year round, all day use, rather it is built for light use, 2-4 hours a day
  • Headband style headset has a noise-cancelling microphone for clearer conversations
  • Can be worn on either ear to fit comfortably on almost everyone
  • Hands-free conversations improve your productivity while typing, using e-mail, and taking notes
  • Volume and mute controls ensure clearer calls
  • Headset stand included with the S11 is a safe place to store your headset until your next call
  • Easy installation on a single or multi-line telephone (will not work on a cordless phone)
  • 1 year Plantronics manufacturer’s warranty
