Wirklich schade, denn die Maus hat mir gefallen. I don’t have any issues with cheap metals or allergies so I can’t help there, but if you want to make these work for a long while, just put a dab of really strong glue. And I can’t help but wonder if they would look a little better as my foot pretty much fills the whole width, but I’m not curious enough to mess with ordering a Wide and having to send a pair back. Die Hülle passt perfekt und die 2. And they are colorful perfect! Sound quality is amazing, noise cancellation is awesome, life of battery great have changed the again since I bought them My daughter has flat feet, so she wasnt even able to wear flip flops for a few years until we found these. Still comfy, a plus (4+ stars) Metal hooks keep it in place. One side is more comfortable, fits better and looks better, the other one has defects, I can see glue and its terribly uncomfortable!
