Key Features
Designed for those with an active lifestyle, the JBL Endurance Race TWS True Wireless In-Ear Sport Headphones feature a water and dustproof design that makes them ideal for working out or hanging out at the beach. They can even handle being submerged in up to 3.3' of water. With an ergonomic wing enhancer and Twistlock technology, the earbuds alleviate pressure point discomfort, while providing a secure fit during vigorous workouts.
Throughout the rest of your day, you can enjoy your favorite podcasts and albums while still being able to stay connected with others. Activate Ambient Aware to better hear your surroundings, or use TalkThru to have a quick conversation with someone nearby, all without having to remove the Endurance Race earbuds. For those farther away, use the dual beamforming mics to make clear hands-free calls. All of this and more is possible all day long with up to 30 hours of total battery life with the included charging case.
