The Speedphone 500 with HD Voice achieves a significantly improved sound quality. This is enhanced in the design by the loudspeaker detail, with top-quality perforated sheet inserts. The clear design of the user interface and the ergonomic shape make it very easy to use. The tapered back and the flat charging unit create an overall impression of being elegant. Square design elements and the corporate font as brand signature elements create a formal reference to the new Telekom design language. Telekom icons on the user interface offer easy orientation and contribute to “One Experience” for Telekom customers.
