JH Laboratory Formula 4 Tonearm

JH Audio was founded in 2007 by Jerry Harvey, a legendary touring sound engineer with over 40 years of professional experience in live audio. Based in the United States and handcrafted domestically, the company emerged from Harvey's earlier success with Ultimate Ears, which he founded in 1995 and sold to Logitech in 2005. JH Audio represents Harvey's return to the custom in-ear monitor market with a focus on uncompromising design and innovation.

The brand specializes exclusively in custom in-ear monitors (IEMs) for professional touring musicians, sound engineers, and discerning audiophiles. JH Audio's product line includes flagship models such as the JH13 Pro and JH16, alongside the Siren Series, which introduced groundbreaking designs like the Roxanne—the first 12-driver IEM to achieve exceptional dynamic range and phase accuracy. Each monitor is custom-molded to individual ear anatomy, ensuring optimal fit and sonic performance.

JH Audio occupies the premium tier of the IEM market, commanding respect as an industry standard-setter among professionals and high-end audio enthusiasts. The company's reputation rests on relentless innovation, meticulous craftsmanship, and a track record of sonic breakthroughs that have repeatedly redefined professional in-ear monitoring. This positioning reflects both Harvey's storied engineering pedigree and JH Audio's consistent delivery of sonically advanced products that serve the world's most demanding listeners.
