The JayBird BlueBuds X Premium Bluetooth Buds combine wireless convenience with amazing sound to keep you rocking out to your favorite tunes whether you're working out in the gym, skiing the slopes, trail running in the mountains, or climbing at the crag. Unlike most Bluetooth headphones, Shift Premium Bluetooth Audio decompresses sound bytes in such a brilliant way that it can retain audio fidelity for perhaps the purest sound available, as good as or better than from comparable wired headphones. PureSound technology enhances your auditory pleasure filtering out white noise to prevent listener fatigue for hours of pure enjoyment. Because JayBird wants you to get the most out of your workouts without worrying over your headphones, the technicians built the BlueBuds X Premium's housing out of Liquipel sweat repellent nano technology for added protection from your own sweat as well as other elements. In fact, Jaybird offers a lifetime warranty against damage from sweat. Whereas most earbuds rest on the bottom of your ears, these utilize an X fit design to hug the tops, backs, and bottoms of your ears for a completely secure fit that won't pop out while you're running, jumping, twisting, or falling. You can wear these wireless buds in the traditional style that most wired or wireless headphones have, or you can wear it over your ear to keep it off your neck for even more comfort. To give you the best fit, JayBird included three different sized buds to deliver a custom fit. The BlueBuds also feature SignalPlus to eliminate signal blocking whether you have your smartphone in your back pocket, backpack, or on the side of the river while you're fishing.
