These JBL Wave Flex earbuds use JBL's Deep Bass Sound to give you high-quality audio with plenty of low-end thump. You'll feel every beat of your perfectly curated playlists when you're out and about. Plus, these babies have an IP54 rating which means they're water and dust resistant, so they won't let you down even if the Great British weather does. And the ergonomic open stick design lets you hear every note clearly without blocking your ear canals - they're so comfortable you may even forget you're wearing them.
