I bought this headset because the model HDW-14322-001 from AVM is listed both by reviewers as being suitable for the Fritz Phone. But it does not work (at least not this version). While it can be connected and "configure". And you can hear something - but rather dull. But the microphone picks up only a little, if it stops in front of the mouth and then it's still pretty quiet. Unfortunately no use. Luckily it was quite cheap - so cheap would it return nonsense.
