Tranquility Headphones - Runner’s headphones with formable rubberized metal hooks that go around the ear, and highly formable polyurethane that you squeeze together and put in your ear to make them fit snuggly and tight.
The hooks prevent the headphones from falling of when you are exorcising and running, the wires go into a Y-shape that you can deside if you want to have in the front of the torso, or in the back of the torso, to prevent the headphones from beeing pulled of.
