The microphone on your CRESCENDO 50 picks up the background sound. Using the user-friendly controllers, you can steplessly choose the volume that suits you and a comfortable level of sound. The sound is delivered straight to your ear via a very lightweight, comfortable under-the-chin receiver, giving you an excellent understanding of the conversation around you, of the TV or radio programme that you are following or at events. Selected accessories widen the range of possibilities of your CRESCENDO 50, e.g. with inductive direct transmission of signals to your hearing aids via the teleloop or with other comfortable designs of headphones. Another comfort feature: Your CRESCENDO 50 hearing amplifier also plays back the signals from loop amplifiers, for example in churches or function rooms.
