No wires. No stopping you.OUR FIRST TRULY WIRELESS IN-EAR HEADPHONES. Get clear, powerful sound from our first truly wireless in-ear headphones. They're engineered to stay in place and stay comfortable. We've packed them full of technologies so you can push your workout to the next level. BETTER EARBUDS BY DESIGN When it came to the tech inside these earbuds, we focused on every little detail-from tuning the circuits for improved sound to tweaking the antenna position for maximum Bluetooth® signal strength. The result? Headphones that play consistently and clearly whether your phone is in your hand, in your pocket, strapped to your arm or sitting on top of the treadmill... and there's never a wire in sight. In-ears that stand out, but stay put These headphones have an unmatched combination of comfort and stability. That's because we engineered the nozzle of our StayHear+ Sport tips to spread contact evenly around the inside of your ear, while the fin conforms naturally to the shape of the upper ridge of your ear. They won't fall out, but they will stay comfortable. And you can focus on reaching new heights in your workouts. Peak power for peak performance A better athletic performance takes years of effort. The same is true with engineering the performance of headphones. And we've been working on it for decades. The volume-optimised EQ and Bose digital signal processing make music sound full and balanced at any volume. No matter how crowded the gym is, your workout playlist will keep you energised. Sweat. Without sweating it. Water and headphones typically don't play nicely together. But we have found a way to make it work. By using a water-repellent mesh in the open ports, we can keep what's inside dry and fully functional. These earbuds aren't afraid of sweat or rain-and now the weather can't be an excuse to skip a workout. MUCH MORE THAN A CASE Off a single charge, the earbuds play for up to five hours-long enough to power you through almost any workout. And when you're done, place them in their case to recover. It'll keep them protected and provides two additional full charges (or up to 10 hours of battery life) to keep them ready to go again. Plus, a quick 15-minute charge will give you 45 minutes of battery life. 774373-0020
