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 and 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. Up to 32 hours of playtime, plus speed charge Your JBL Endurance Zone earbuds have enough power to run a marathon. With up to 8 hours in the earbuds and another 24 in the carrying case, you can make it through a week's worth of training runs or gym classes before you need to recharge. Need a quick top-up? 10 minutes of charging via the USB-C cable* will give you another 3 hours. *Not included Convenient to carry Keep your earbuds close at hand. The rugged, durable charging case has a lanyard hole so you can keep them within reach in or on your bag.
