The Lola™ Custom IEMs feature Dual Low and Quad High Balanced Armatures and Dual Dynamic 4.9mm Drivers that utilize patent pending D.O.M.E™ Midrange Enclosure Technology

Redefining IEMs Using Hybrid Technology

Jerry Harvey designed the industry's first 2-way custom IEM 25 years ago after Alex Van Halen asked him to look into In-Ear Monitors. Since then, Jerry has continued to innovate, redefine, and lead the industry in both the Professional Touring and Audiophile markets.

Once again, Jerry Harvey introduces a new paradigm shift in what an IEM can do with the introduction of the Lola™ Hybrid In-Ear Monitor.

Magic in the Midrange

Custom IEM designs have primarily used Balanced Armatures due to the size limitations of the custom shell. More specifically, in Hybrid designs, using dynamic driver technology as Bass drivers is a popular choice. Jerry Harvey's breakthrough quad driver designs use multiple Balanced Armatures, and when implemented correctly have very tight, accurate bass response and great high mid to high frequency extension. However, Jerry felt they lacked warmth and air in the mid bands from 200Hz to 3kHz.

With Jerry's history of working in live audio reproduction, he has tuned 100's of large arena PA systems and has long favored the natural, airy sound of 12 inch Dynamic cone midrange drivers. The task was to overcome the limit of size.

Innovation: D.O.M.E™ Technology

Jerry Harvey and his all-new patent pending D.O.M.E™ (Dual Opposed Mid Enclosure) technology brings a new design. In order to get the response he was looking for in this new piece, Jerry sourced 4.9mm dynamic drivers and designed a phase-correct band pass enclosure to house them inside the IEM. This tuned enclosure is custom 3D printed in their lab and holds two 4.9 dynamic drivers, giving Lola a 9.8mm effective midrange driver in a small package.

Lola's Hybrid design utilizes a proprietary Dual Low Balanced Armature covering from 10Hz to 200Hz, the mid utilizes D.O.M.E™ technology which handles 200hz to 3kHz, and a Quad Balanced Armature from 3khz to 20kHz.

Lola™ also features Freqphase™ technology, proprietary 4-pin or 7-pin connectors, and 10dB of user adjustable Bass response - famous in JH Audio IEMs.

Now with Acoustic Sound Chamber™

The Acoustic Sound Chamber is a bowl-like area created to recess the tubes in the ear canal. This 3D printed, recessed tubing system is the first of its kind, keeping sweat at bay and alleviating the need for excessive cleaning. This recess helps catch wax and sweat from your ears and makes it easier to clean your IEMs.
