Description: If you spend a lot of time on the phone, this headset will give you flexibility and freedom you never had before. ECO-DECT technology reduces power output and radio frequency of the headset, while still retaining the quality of the audio. Unlike most other DECT headsets, when the headset is docked in the base station in standby mode, the headset practically stops emitting radio frequency. This reduces the RF emissions to almost zero. When the headset is in use, the ECO-DECT technology ensures a safe power output, with minimal emissions. The headset adjusts the radio frequency power output in four steps depending on the distance between the headset and the base: the closer to the base, the lower its power output. Features wireless range up to 500 ft and talk time up to 7 hours. Optimized for Microsoft Lync, Skype for Business, Skype and other VoIP platforms.
