The JBL Reflect Mini BT are basic Bluetooth earbuds. Via Bluetooth you stream your favorite songs wirelessly from your smartphone. The earplugs are sweat resistant, so they don't break after a workout. Thanks to the reflective neck cable, you can also exercise outside in the evening. This way, you'll be visible and your workout will be a lot safer. The earbuds last up to 8 hours on a full battery.
