​D.O.M.E (Dual Opposed Mid Enclosure)

​The Lola in-ear monitors feature dual low and quad high balanced armature drivers and dual dynamic 4.9mm drivers that utilize D.O.M.E Midrange Enclosure Technology. Jerry sourced 4.9mm dynamic drivers and designed a phase-correct band pass enclosure to house them inside the Lola™. This tuned enclosure is custom 3D printed in the lab and holds two 4.9mm dynamic drivers that oppose each other, giving Lola a 9.8mm effective midrange driver in a small package.

frēqphase Time | Phase Waveguide

frēqphase™ time phase steel tube waveguide corrects time and phase of multiple drivers. By reengineering how and when sound is traveling to the ear, the waveguide, JH Audio created the first phase coherent earphone by delivering the low, mid, and high frequencies to your ear at once.

Jerry Harvey Audio's proprietary mini quad drivers.

Variable Bass Output Adjustable Cable

User controlled low frequency drivers with adjustable bass output. 

​JH Audo custom in-ear monitors offer superior noise isolation, eliminating stage volume and ambient noise, critical for performing musicians and audiophiles alike. This extreme ability to block outside sounds enhances the listening experience and allows for lower listening levels reducing the potential for hearing damage.

A St. Louis native, Jerry Harvey grew up with a passion for music and a flare for audio. That passion combined with an eagerness to learn allowed him to turn running sound in local venues into touring with some of the biggest names in music history. In 1994-1995, in-ear monitor technology was in its infancy. As Van Halen’s monitor engineer, Jerry was presented with a challenge to find in-ear technology that would work for drummer Alex Van Halen.  Jerry funneled his experience tuning large arena sound systems and engineered the first 2-way, custom-fit earpiece just for Alex. Before long, Harvey was designing and manufacturing in-ear monitors for touring musicians, crew, and soon audiophiles.
