The Jerry Harvey Audio team has been working for over a year to design these new universal fit iems to fit more like custom iems. The new shells are made with state of the art 3D Printing Technology to reduce the size by ~40%. This ensures proper fit, retention, and an acoustic seal for a custom-like IEM experience!
THE STORY of JH Audio Performance Series IEMs
Many people struggle to get Universal IEMs to fit and seal properly. This is a crucial component for getting good bass response and taking advantage of the sonic performance of any earpiece. The team responded to the consumers' feedback and decided to embark on a yearlong study to perform a proper analysis.
JH Audio has handmade thousands of Custom IEMs for Top Artists around the world. With over 30,000 sets of ear molds in their Orlando Lab to reference, JHA successfully analyzed the fit differences and ergonomics of Custom versus Universal IEM shells.
Custom fit IEMs are made from exact impressions of the human ear and share certain geometry and angles.
One of those similarities is a 10% up angle of the sound bore.
The new sound bore adjustment, in addition to the refined shape of the ear bowl and helix area, provides a custom-like fit & seal like no other Universal IEM.
In order to achieve the new Universal IEM shell shape, JHA is utilizing both 3D Modeling and 3D Printing technology. They invested in a new, Quarter of a Million Dollar 3D Printing system. Every angle on the new shell and sound bore has been carefully redesigned to provide the user with a smaller overall shell size and a more naturally fitting sound bore. These adjustments allow users to more easily position the earpiece for optimum fit inside the ear. You can ensure a perfect seal and comfortable fit every time.
This shell design is only achieved through 3D printing processes. Then, JH Audio individually assembles and finishes each Universal IEMs by hand. Afterward, the team tests and matches each IEM within 1db +/- of their reference curve. This level of attention to detail and craftsmanship is unheard in the industry. Most manufacturers only match within 3db +/- of their reference curves.
JH Audio introduces the Performance Series with their most popular and highly reviewed IEM’s in the Pro and Audiophile communities. The JH16v2 Pro, JH13v2 Pro, and Roxanne IEMs are currently used by some of the biggest Touring Artists in the world including U2, Garth Brooks, Lady Gaga, Guns & Roses, Maroon 5, and many more.
