Hybrid open-ear headphones with detachable neckband JBL Soundgear Sense true wireless open-ear headphones feature JBL OpenSound Technology with air conduction, which doesn't completely close off your ear canal, making them comfortable enough to wear for hours. Flexible earhooks rotate, so you can choose whether you want to focus on your music or calls, or let in more sound from the world around you. A detachable neckband provides an even more secure fit while you're working out, and an IP54 rating means that they can stand up to sweat or even a light rainfall. Your voice will be crystal clear, even on a windy day, thanks to four voice mics. Customize how you use the intuitive touch controls on each earbud to handle your music and calls with the My JBL Headphones app. JBL Soundgear Sense is as adaptable as you are.
