Its extremely ergonomic in design and comfortably sits in my ear. whoah, how can this sound so good, then I thought others could hear it and no one could hear anything while I had them on. These are sturdier than I expected and were easy to put up. I also love that the materials keep my feet warm but still allows them to breathe, unlike cheaper brands with man made materials I have tried in the past. But it still does a great job at helping sweat in the right area when at the gym, and the extra strap across the stomach is a huge help! When I added a belt, all the extra material flopped over the belt and it just looked like a mess. and stumbled upon a true godsend. Not for bass lovers but delivers a well balanced sound for all music. The finger lock is covered by thin plactic so no water or dust can get on your device. As a chef I’m on my feet all day.
