JBL OpenSound Technology OpenSound technology in the JBL Soundgear Sense earbuds provides a natural sound experience, with almost zero sound leakage. Thanks to this innovation, the sound waves are directed towards the ears, and at the same time, an opposite phase reduces sound dispersion. You enjoy your sound, while your privacy is protected. The JBL Soundgear Sense rests on the curve of your ears without obstructing your ear canal, so you can hear both your sound and the world around you in full comfort. Enhanced Dynamic Sound Two smartly designed 16.2mm drivers—one per each earbud—feature a unique bass-enhancing algorithm, providing an amazing no-compromise sound experience with punchy bass and pure sound, allowing you to enjoy every beat. Up to 24 Hours of Battery Life and Fast Charge For long-lasting fun, listen wirelessly for up to 6 hours and get another 18 from the included charging case. If you're in a hurry, use the included USB-C cable for a quick 15-minute charge, which gives you 4 additional hours of music. Hybrid Design The adjustable earhooks offer comfort and stability for all-day use. Going for a run? The included neckband provides an even more secure fit, so you won't lose an earbud while you're working out. Dual Connect and Sync with Fast Pair Flip open the case and your earbuds pair with your device automatically. Use both earbuds together, or use either one individually, thanks to Dual Connect.
