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.
