Additonal features

  • DECT Wireless Technology

    • Better sound, wider range

      The Sennheiser SD Wireless Series uses DECT (Digital Enhanced Cordless Technology), which has become one of the most commonly used technologies for wireless communications. With DECT, your SD headsets operate on a special frequency, giving them better sound quality while eliminating static and distracting sounds. With DECT your SD headsets have a much wider range allowing you to move around in the office without losing signal strength.

  • Ultra noise-cancelling Microphone

    • Ensuring your message gets through clearly
      In a busy work environment, background noise can be a distraction - especially for your listener. The SD series is equipped with noise-canceling and ultra noise-cancelling microphones which filter out background noise, so you and your listener can better concentrate on the conversation.

  • Intuitive call control

    • Answer/end a call, mute microphone and adjust volume directly on the headset.

  • Sennheiser ActiveGard®

    • Hearing Protection Technology

      Heavy phone users may be exposed to potentially dangerous acoustic shock from unexpected and extremely loud sounds on the line. Sennheiser ActiveGard® technology protects users against acoustic injury caused by sudden sound bursts on the line.

  • Full work day talk time

    • No excuses for breaks - We’re sorry.

      With the SD series, you get 8 hours talk time in wideband and 12 hours in narrowband sound mode. This way you can work all day without unplanned interruptions.
