Product information

The Sennheiser DW Office cordless headset connects to both desk phones and PCs and comes with two stylish wearing options.
With its sleek modern design, this cordless PC headset is ideal for people who spend much of the day talking on the phone, either on a traditional analogue line or on skype or other softphones. The Sennheiser DW OFFICE connects to your office phone via  an RJ11  telephone cable and to your PC via USB.

You can easily switch between telephone and PC calls with a one touch button on the base. The DW Office is an extremely comfortable headset, with a generous talk time of 8 hours, making this an ideal headset for all-day use. It comes with both a headband and an earloop, so you can choose the style that most suits you, and its monaural style means that you can keep one ear on what is going on around you whilst talking on the phone.

Sennheiser is world famous for the incredible sound quality of its microphones and headsets, and the DW Office is no exception. Its noise cancelling microphone filters out background noise so that you can be heard perfectly by the person you are talking to and its wideband sound delivers face-to-face quality conversations.

The Sennheiser DW Office Cordless Headset also provides protection against acoustic shocks, thanks to the integrated ActiveGard technology, which automatically limits volume to a maximum of 85dB.

With a range of 180m in open spaces and 55m in offices, the DW Office gives you the freedom to move around freely and work at the same time as you talk. This model is ideal for use with handset lifters and electronic hook switches, which make it possible for you to answer and end calls without being next to your telephone.
