Sennheiser OCX 685i

18 - 20000 Hz, 120 dB, 16 ohm, 1.2 m Spend more time on your training with the OCX 685i SPORTS headset as it features comfortable earclips that are not only intuitively self-adjustable but also, lightning quick to put on. The earclips stay secure to your ears so you no longer have to worry about them falling out or dislodging when you are pounding along on the treadmill. The ear-canal coupling attenuates well, while the cable routing minimizes structure-borne noise, therefore you are able to have your choice of music inspire and spur you on, at the same time.
