Amplify your performance with the JBL Endurance Race 2 wireless sports earbuds. With up to 48 hours of battery life and an IP68 water- and dustproof design, they help you keep going thanks to the powerful JBL Pure Bass sound system that delivers bold sound with rich bass. With improved sealing and stability, the superior fit provides all-day comfort from the beach to the trails to the gym. This audio device uses an active noise cancelling system paired with the Smart Ambient technology to filter out distracting noise while letting you control how much of the outside world you want to hear, so you can talk with others or stay aware of your surroundings. Plus, you can enhance your workout by adjusting the settings of your earbuds to match the intensity of it through the JBL Headphones app by choosing from one of the six default Sport modes or by creating your own. And when it is time to cool down, you can select the Relax mode and hear one of five peaceful sounds, like gentle ocean waves or a crackling wood fire. With the ability to make crystal clear calls from anywhere and get help from your preferred voice assistant, you can stay connected to the world no matter where your workout takes you.
