Introducing the all new Jaybird X3 wireless earbuds. These secure-fit, sweat-proof premium sport buds delivering superior audio performance (music & calls) in a sleek helmet compatible metal accented design. With 8 hours of play time you get a full week of workouts on a single charge. A 15 min quick charge gets you a full hour of play time. Customize your sound with the Jaybird MySound App and save your unique sound profile to your X3 buds.

The 3rd generation of the iconic Jaybird X-Series is now even smaller with much bigger sound, better battery and our most secure-fit ever. We're bringing full helmet compatibility and the MySound App experience to the X-Series for the first time. Weapons hot!

Our legendary X-Series battery life continues, and gets better. Now you get a solid 8 hours plus for a full week of workouts on a single charge. Only 20 min of quick charge gets you a full hour of playtime. Batter-up.

We redesigned the Bluetooth antenna architecture from the ground up to ensure skip-free music outdoors – so you never miss a beat.

With double hydrophobic nano coating and redesigned super-tight seams we’ve got you covered in the rain, mud, sun, sweat and tears – these buds will take a beating, and go wherever you go – and then some!

We reduced the size and improved the fit. We redesigned the fins and went super-ergo for a solid secure comfort fit – these buds are sticking with you no matter how crazy active you get.

No more complaints of too much or not enough bass. Now you can customize the way your X3’s sound and save those custom sound profiles to your buds, no matter what music device they’re paired with or what music service you use. It’s your playlist – you’re now in control.
