History
H2O Audio was started as a graduate student project at San Diego State University by a SCUBA diver who wanted to take music with him while diving; hence the company was originally named Diver Entertainment. In 2002, the first patents were approved, followed by the development of waterproof technologies in 2003. By 2004, the first underwater SCUBA product was shipped. In 2005, the company moved into developing waterproof headphones and cases for MP3 players, including iPods. 2007 was the year Olympic swimmer Natalie Coughlin was brought on as the first official H2O Audio Ambassador, and in 2008, big wave surfer Laird Hamilton was also named an official H2O Audio Ambassador. Currently, Laird Hamilton has his own signature version of Surge Headphones. In 2009, Olympic swimmer Michael Phelps also became an official ambassador of the brand, along with triathletes Greg and Laura Bennett.
