COMfortel® M-520

First impression: attractive and high quality. Second glance: practice-oriented and powerful. With the COMfortel M-520, the exterior goes hand in hand with the inner values without compromise.

Its clear advantages can be seen and felt at first glance: the large display dominates the front section stylishly and blends seamlessly into the smooth surface made of high-quality polymer, which envelops the pleasantly wide yet extremely flat telephone. Once in your hand, you don't want to put the sturdy lightweight away.
