So, I got me the part now zugelet times. I have to say while jogging sits really well. It is comfortable and does not interfere. In addition, the processing Top. I now have not respected it, how fast it is dry again after jogging, but nen day later it was dry again ;-). So now time to Bedinung while jogging. That with the lock in my opinion is not a big problem. I'm just out there, as there is no problem in my opinion is the dan times öffters to hang on the wall socket. And otherwise the Bedinung is super easy to select in advance what you want to hear (Artist playlist or so) and Dan can easily if you have the bracelet on, forward / back coils do Play / Pause louder and softer.
Conclusion: The money is worth it. And it looks great in my opinion ^^
