OpenSound technology in the JBL Soundgear Sense earbuds provides a natural sound experience, with almost zero sound leakage. Thanks to this innovation, the sound pressure is directed through waves towards the ears, and at the same time, an opposite phase reduces sound dispersion. You enjoy your sound, while your privacy is protected. Also, the JBL Soundgear Sense rests on the curve of your ears without obstructing your ear canal, so that you can hear both your sound and the world around in full comfort.
