Don't sacrifice great sound when you hit the gym. Audio-Technica's ATH-CKP500 active-fit in-ear headphones feature ergonomic C-shaped eartips that nestle naturally in the outer ear to hold the headphones securely in place. Their angled housings direct the cord behind the wearer's neck so it stays out of the way. In addition to standard sound isolating eartips, the ATH-CKP500 comes with newly designed ridged eartips that allow the user to hear ambient noise like traffic or other runners for safer use outdoors. The headphones have IPX5 Waterproof Certification that allows them to be washed after use. They are available in black, red, white and blue, and come with a cord clip and 2-ft. (0.6 m) extension cord.
