The JayBird X2 Wireless Headphones help you survive leg day in the gym, enjoy fresh pow days on the slopes, and relax at the beach on the weekend. These hand-free headphones connect wirelessly through Bluetooth and blast your tunes with a 20Hz-20KHz frequency response, which is ideal for your active lifestyle. A silicone carry case conveniently holds your headphones as you travel, and the USB charging cable helps keep your music playing for up to eight hours. And since they have 6mm drivers, they deliver warm bass with the frequency response tuned to emphasize sub-bass.
