Results matter, and when you have the perfect headphones there’s nothing standing in-between you and your workout. With their FlipHook design, they adapt to an in-ear or behind-the-ear fit for added convenience. A comfortable combination of FlexSoft ear tips and TwistLock technology means these buds are guaranteed never to hurt or fall out. And if you thought a little sweat or rain was going to ruin your run, think again. Thanks to IPX5 sweat-proofing, JBL Endurance RUN headphones keep up with your every step, while an in-line microphone and remote ensures you’re never reaching into your pocket to answer calls.
