We test the sound quality of our DECT phones the same way as high-end headphone manufacturers do. Using an advanced ear simulator, we can accurately re-create the way people actually hear. This helps our acoustic engineers to measure and fine-tune things like frequency response, distortion and overall hearing perception, to create perfect voice reproduction.

Automatic Volume Control offsets variations in sound signal, which can be caused by distance, signal strength or the caller's phone — so what you hear always remains consistent. Reducing the audio amplification for strong signals, and increasing it for weak ones, means you can enjoy a smooth conversation without unwanted sound volume variation.
