Jerry Harvey began designing custom in-ear monitors (IEMs) in the mid-1990s when he was a sound engineer for Van Halen. Jerry founded Ultimate Ears and in 2007, Jerry Harvey Audio (JH Audio) was born. Today JH Audio produces some of the world's best custom and universal fit IEMs for audiophiles and musicians.

Jerry's series of IEMs made in collaboration with Astell&Kern can be found on the Astell&Kern Headphones page.
