Experience all your calls in top-notch clarity. Four microphones with noise cancellation and exclusive WindSmart technology capture your voice while filtering out wind and distracting background noises, ensuring your voice is loud and clear on every call. Enjoy lasting comfort even on long days with the smallest and lightest earbuds. The ultra-comfortable and uniquely designed ear tips provide a snug fit without going deep into the ear canal. With three different sizes of ear tips, you’ll always get a perfect fit that won’t slip. Dustproof, sweat-resistant, and waterproof with an IPX4 rating means you can take calls or listen to music anytime, anywhere—even in rain and humidity. Plus, you can store your earbuds in a sleek, portable charging case that allows you to enjoy up to 13 additional hours of music between charges. When you’re in a hurry, a quick 10-minute charge gives you up to an hour of listening time. Additionally, the earbuds automatically power on and connect to your mobile device when you take them out of the case—making it easy to answer a call or play your favorite song.
