Am Tag drauf dann mit einer Bekannten und ihrem 30k wieder das intercom ausprobiert. The battery has yet to go below 50% with nearly 5 hours a day in 4 days! These earbuds are great for running and listening to music. Theses are very nicely made shoes. As a person who has pretty wide feet, it can be hard to find cute and comfortable shoes. Also seeing this shoe sold under different names made me doubly skeptical that these could even be a decent shoe. I originally gave 4 stars due to sizing, but I updated to 5 stars because they are just a wonderful shoe for me. They are very good earbuds in that I have no problem with the sound or the mic. Zudem ist sehr praktisch, dass es eine Anzeige gibt, welche zeigt, ob die Controller voll geladen sind. No buckling, no blowing around, nothing.
