Thanks to the generous address book for up to 500 entries and the convenient data synchronization with the Outlook contacts on your PC, you are also well-connected. Excellent acoustics are a given for the Gigaset S850 HX: with a single click, you can switch between three audio profiles and optimally adjust the acoustics to your environment.
