Take calls and issue voice commands even when your phone is in your hand or pocket. Additionally, the high-quality built-in microphone makes it easy to make and receive calls on your smartphone. When the rain pours down, splash-resistant headphones play your music during your workout. Sound flows in and out through the back of the ear cups for a more natural sound. Enjoy more freedom of movement with a cable that's long enough for the treadmill or the road.
