Results matter, and when you have the perfect headphones, nothing is standing in-between you and your workout. The JBL Endurance RUN comes with a FlipHook™ design that adapts an in-ear or behind-the-ear fit for added convenience. In addition, 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 sweatproof, 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.
