Designed especially for active use, the ATH-SPORT1iS SonicSport in-ear sports headphones combines all the features of the ATH-SPORT1 with smartphone capabilities. A universal in-line mic and controls allow you to answer/end calls, control music and adjust volume at the touch of a button. Like the ATH-SPORT1, the hinged ear hooks pivot to provide a custom fit for secure, long-lasting comfort. Featuring high-quality drivers for clear, detailed and dynamic sound, the headphones come with both standard silicone eartips (XS/S/M/L) for outstanding sound isolation and ridged eartips (S/M/L) to allow some ambient noise for safer use outdoors, making the ATH-SPORT1iS ideal headphones for running. The sport headphones are IPX5 Waterproof Certified, which allows them to be washed after use. The 3.9 ft. (1.2 m) cable comes with a clip to keep the cable conveniently fastened to clothing during workouts and other active use.
