About Plantronics Savi S8240 Office - DECT Wireless Headset - Convertible - PC/Deskphone/Bluetooth (8D3H4AA)

The Poly Savi S8240 Office is a wireless DECT headset built for busy desks where calls come in from every direction. It connects to your desk phone, computer, and mobile at once, with one-touch controls and a flexible boom mic that cuts background noise. Three wearing styles are included in the box, so you can pick the fit that suits you and get on with the day.

Key Features

  • 3-Way Connectivity — The base links to your desk phone, PC via USB, and mobile over Bluetooth, so you can take any call without swapping gear.
  • Long DECT Range — Up to 180 m in open areas and around 55 m in a typical office, giving you room to grab a coffee mid-call.
  • Clear, Private Calls — A noise-cancelling microphone and close conversation limiting keep your voice sharp and your chat contained in a busy open-plan office.
  • Convertible Wearing Styles — An ear hook, behind-the-head neckband, and over-the-head headband are all in the box, so every user can find their comfort zone.
  • All-Day Talk Time — Up to 7 hours of talk time and 30 hours on standby, with the charging cradle ready between calls.
  • One-Touch Controls — Answer or end calls, adjust volume, and mute from the headset, with spoken prompts for mute status and range.
