Sennheiser OCX 686 Headphone.
Sennheiser’s OCX 686 SPORTS has been created to energize your music experience while you concentrate on your sets and reps, or knocking out the miles on the road/treadmill. Enjoy your favorite music at the gym without distractions with great isolation from the in-ear design. Super secure fit is achieved with the ear-hooks to help keep the OCX 686 in place no matter how intense the work-out. The cable is a bit awkward because it's a 'J' type which means the right side is shorter than the left. Built in controls for volume, pause/play, and a microphone for any Apple/Android device. Sweat and water resistant, plus a 2 year warranty of protection from Sennheiser.
