Jerry Harvey didn't come up in a lab coat; he came up in the audio trenches.
Born in St. Louis, a city built on music and grit, Jerry grew up with equal parts curiosity, hustle, and a borderline obsession with sound. By his teens, he was running audio at small venues; not long after, he was mixing on the biggest stages on earth for some of the most demanding artists in history.

In the mid-90s, touring acts still relied on wedges, and the few IEMs that existed didn't hold up on real stages with real musicians. As Van Halen's monitor engineer, Jerry was tasked with solving a problem no one else could: finding something that worked for Alex Van Halen. Disillusioned with every available option, he engineered the first two-way… read more custom-fit IEM. Word spread fast. Soon, other engineers were knocking, artists were lining up, and Jerry found himself at the forefront of an audio revolution.

Jerry's first company, Ultimate Ears, introduced multi-driver in-ear monitors to the world and changed touring forever.

After another decade of refining IEM development on the road with the likes of Aerosmith and Pearl Jam, in 2007, he formed Jerry Harvey Audio. From the classic 'reference JH13 and JH16 IEMs, came the Siren Series, including Roxanne, the first 12-driver IEM with independent adjustable bass and a phase-accurate waveguide system that pushed the entire industry forward.

Jerry wasn't satisfied stopping at customs, either. After years of studying fit, shape, and seal, he built a universal shell that mimicked the comfort of custom molds while reducing the size by 40%--the result: universal EMs that finally met professional expectations.

That same drive led to the evolution of his first 'Digital EM', the Pearl system. A tri-amp, micro-speaker management processor delivering ultra-low latency and 96kHz resolution with independent control of lows, mids, and highs. Built for the realities of modern touring, it delivers unprecedented precision in the IEM signal chain for engineers and performers. To complement that level of control and Pearl-powered tuning flexibility, Jerry developed the elite Ruby 2, a powerful 10-driver EM (quad lows, dual mids, quad highs), and the Rosie, a dual-low, dual-mid, dual-high IEM design.

Today, Jerry Harvey Audio continues to innovate with 12 custom models, a growing universal line, and a relentless drive to push boundaries. With the brand now joining forces with Sound Devices and Audiotonix, industry leaders in production audio technology, the mission is bigger than ever: combine world-class engineering with real-world touring experience to shape the future of professional audio.

Jerry's story isn't about theory. It's about living on the road, solving problems in real time, and building products that endure the chaos of actual stages. No one has more hands-on experience, more tour miles, or more direct artist feedback fuelling their designs.

And that's why his work doesn't just follow the industry. It leads it.
