The Shokz Openrun Headphones are bone-conduction headphones for running. The wireless design won't get you tangled up in any cords while on the move and is incredibly lightweight at 26 grams. The IP67 waterproof rating allows for every daily run, rain or shine, and won't blink an eye at a little sweat. The open-ear style provides incredible comfort, and keeps ears clear for awareness, so you can tell if you've got a bear rustling on your left, or just a car coming.
