Listen to music while running with the JBL Endurance RUN. The earbuds have ear hooks, so they won't fall out when you're working out. The ear hooks allows you to wear the earbuds either in-ear or behind-the-ear. Play music from your own playlists on your smartphone or stream music from a streaming service. You can easily control the earbuds with the in-line controls. Control your music, the volume, and phone calls with 1 push of the button. Are you planning on doing a high-intensity workout or a boot camp in the park? Thanks to the splash-proof design, the earbuds can withstand a little rain and sweat.
