Founded in 2007, Grace Digital Inc. is based in San Diego, California, in the heart of the Sorrento Valley telecom technology center. The company puts a priority on overseeing every aspect of the making of their products — from design, engineering, and manufacturing to marketing, distribution, and supply chain management. Grace Digital creates technologically advanced, yet elegantly simple communications convergence products.

A signature part of Grace Digital's audio solutions is its line of waterproof audio accessories. The Sonar Premium Headsets are high-quality earbuds designed to keep sound in and water out. The headsets are outfitted with bass boosted sound, and they're completely submergible up to 10 feet. In addition, the Eco Extreme Waterproof MP3 Speaker Case is the perfect underwater audio accessory because it works with virtually every MP3 player. Built with a rugged, rubberized protective body designed to float on water, the waterproof MP3 case is portable and lightweight with a built-in speaker. Grace Digital's waterproof audio solutions provide convenience and top-quality sound for listening to music while swimming laps or relaxing in the pool.
