Designed For Sports : Get a secure, stable fit every time with a high-grade liquid silicone earhook and adaptable memory wire. Even if you wear your earbuds all day long, they'll fit perfectly, no matter how active you get. IP68 Water & Dust Proof : Sweat, rain, salt water, and sand? Sounds like a great time. JBL Endurance Zone earbuds carry an IP68 waterproof and dustproof rating, so they can withstand it all. Not to mention high temperatures, high humidity, or long-distance drops. High Durability For Intensive Use : Both the earbuds and the charging case are made from a rugged, scratch-resistant material. They're also easy to grip, even after a sweaty workout, so they won't go flying when you take them out. And no matter how many times you adjust them, the rugged earhook resists stretching and twisting, so they'll always fit like new. 4 Mics For Crisp, Clear Calls : Two beamforming mics per earbud effectively capture your voice while suppressing noise from other sources. Meanwhile, the beamforming algorithm minimizes unwanted ambient noise, making your authentic voice more intelligible. The hydrodynamic windproof design significantly reduces distortion from air friction and gives you a crystal-clear call experience even in the middle of an outdoor run on a breezy day. JBL OpenSound Technology : Enjoy clear, exciting music buds-free, so you can always hear your surroundings while you exercise. A sensitive 18x11mm dynamic driver delivers crisp, clear highs and round, rich mids, while our adaptive bass boost algorithm provides the beat that keeps you moving.
