Waterproof and dustproof
The JBL Endurance Race 2 is made for your toughest workout. Their IP68 rating means they're fully dustproof and waterproof, with complete protection against solid particles and the ability to survive being submerged deeper than a meter in both fresh water and sea water. Even the charging case is IPX2 water-resistant, so it can come along on your next rainy-day run.
Ergonomic wing enhancer with Twistlock™ technology
The ergonomic wing enhancer on the JBL Endurance Race 2 earbuds uses Twistlock™ technology. That means a better seal and with more stability in your ears when you're using them, not to mention all-day comfort.
Enhance your work-out with 'Sports Mode'
Use the JBL Headphones app to match your workout with ANC, Ambient Aware and EQ. Adjust the settings to the intensity of your workout, choosing one of the six default Sports Modes - or you can customize your own. And when your workout is over, chill out and recharge in Relax Mode by choosing one of five peaceful sounds, like gentle ocean waves or a crackling wood fire.
