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.
