• Ultimate Comfort and Fit: Comes with a pair of shark fins, three sizes of silicone tips (small, medium, and large) for a good fit and best audio quality. The fins work well for active use and can be removed completely if not needed. And you don't have to shove the tip in your ear to get it to stay put. It uses the contour of your ear to hold it in place. You can enjoy them for long workouts.
• Enjoying Your Favorite Music: Good sound quality, especially the good amount of bass without any distortion and good mids and highs without any cracking noises. High volume or low, they handle it. And a nice addition is that the design of the ear tips limits external noise.
• Nice Color-matched Cords & Ergonomic Design: With nice color, you'll always find one that best matches the day's outfit, your audio player and your mood. A comfort-length, 1.2m/3.94ft cord provides the flexibility and comfort needed for an active day, and can be comfortably threaded through a jacket, bag, or backpack. Sweat- and weather-resistant design helps ensure these headphones survive the rigors of your daily life.
