JH Audio is a company founded by Jerry Harvey Audio. Jerry was a sound engineer for Van Halen and started experimenting with IEM's for the Van Halen drummer. The rest, as they say, is history. JH Audio has been making and improving the IEM audio process ever since. The JH13 and JH16's are legendary Customer IEMs in the marketplace, and now he has launched the Roxanne, Angie and Layla available as Universal fit for the audiophile market.
Recently JH Audio partnered with Astell & Kern to create AK tuned versions of the Siren Series Universal fit IEMs. We've reviewed a couple of these on Headphones Canada and know you'll be impressed.
