Enjoy your music with superb sound quality thanks to the adidas Performance by Monster Response ACT sport headphones. They are designed with a patented SportClip that keeps them in your ear, whether using them during daily activities or your workout, and the sound includes thumping bass, unadulterated clarity and a wide dynamic range. The antimicrobial ear tips are both sweat-proof and washable so you can keep them hygienic and clean, and they can be used with helmets, goggles and glasses. With Apple ControlTalk you can control phone calls and music via the headphones, keeping your device in your pocket and your hands free.
