An evolution of the company's earlier waterproof headphone designs, H2O Audio's new H3 Waterproof Headphones ($50) jump up in price, as well. Black rather than white and gray like their predecessors, H3 comes bundled with two sets of rubber earplugs that fit over the left and right speakers, then into your ears; the headphones are submersible to depths of up to 10 feet and work with H2O's current and 2006-2007 waterproof iPod cases.
