Run with the Skullcandy XT Free Wireless Headphones and you'll never accidentally pull a bud out of your ears again. MicroSport Bluetooth connection gives these earbuds wireless convenience in an ultralight, minimal, low profile design. TripleLock technology uses three of Skullcandy's proprietary technologies FitFin, StickyGels, Fix to keep each earbud in no matter what. Sonic welding makes the XT Free ruggedly sweat resistant, and Skullcandy mixed antibacterial PureClean ear gels for more convenience. There's a remote behind your ear for volume control and an added microphone for taking calls.
