SWEAT-RESISTANT: Welded construction protects sensitive components from moisture that can damage or destroy your earbuds. ONCE IT'S IN, IT WON'T BUDGE: Our StickyGels technology is 30% more secure when sweating than standard earbuds, which boosts in-ear stability. Pureclean ear gels prevent build-up of germs, keeping the earbuds fresh and clean.
