Ensuring your message gets through clearly

Noise-cancelling microphone

  • In a busy work environment, background noise can be a distraction – especially for your listener. The DW Office is equipped with noise-cancelling microphone which filters out background noise, so you and your listener can better concentrate on the conversation.

Ease-of-use with a personal touch

Intuitive user interface

  • The DW Office is created with the user in focus and all features are intuitively designed to fit seamlessly into your daily workflow. Built-in call handling makes it simple to answer/end, mute or control volume while moving around the office, while features such as left/right wearing and name plate make it easy to personalize your headset.

A choice of wearing styles


  • In busy office environments, where you may be wearing your headset all day long, the flexibility of changing wearing style can enhance long-term comfort.
  • The FlexFit™ wearing style system offers the choice between a headband, ear hook or neckband solution for the perfect customized fit. The neckband is available as an optional accessory.
  • Long distance wireless range: Walk and talk where you want with an extended wireless range. Experience quality sound on the move as you roam around the office. Wireless freedom extends your working range so you’re always in contact with your phone. In a typical office building DW Office gives you a radius of up to 55 m and up to 180 m in line of sight.

ActiveGard®: Sennheiser ActiveGard® technology protects users against acoustic injury caused by sudden sound burst on the line.
