“Lap swimming is the most healthy, low-impact path to fitness – it engages your entire body, strengthens your heart and lowers stress levels – but it is boring!,” said Kristian Rauhala, CEO and Founder of H2O Audio. “We are pleased to launch the INTERVAL for Apple Watch allowing swimmers to listen to their favorite music, iTunes, Pandora, podcasts or audiobooks while swimming, all directly from their Apple Watch, no phone needed. This new device gives lap swimmers the same level of motivational entertainment that joggers and runners have enjoyed since the invention of the walkman.”

INTERVAL’s rugged sports band securely clips to the Apple Watch and integrates with any set of swim goggles. INTERVAL positions the Apple Watch comfortably and securely behind the swimmer’s head while the included 10-piece set of custom waterproof eartips allow for the perfect fit for any swimmer. INTERVAL employs H2O Audio’s proprietary industry-leading underwater speaker drivers for clear and powerful sound under or above the water.
