“ The JH13 Pro was my first purchase of high-end personal audio equipment so it's difficult for me to provide a fair comparison (prior to purchasing them, I was listening to iPhone earbuds), but I can safely say that I couldn't possibly be happier with my purchase. The process of getting the impressions made was painless (albeit a bit expensive in the San Francisco Bay Area), and...” --WKHarmon
“ I orederd a pair of JH 16Pro IEMs in May. It is now June 15th. Since ordering the first pair, I have returned at my cost of $21.15 each time, the IEMs three times. Each time, Caleb Ellis, who manages the department that makes the IEMs, said he could not explain what had happened. The left IEM of the first pair fitted perfectly with the impressions I paid an ...” --rollinoswald
“ I posted a few pictures elsewhere, but now I’m making a dedicated thread about it. The topic is Heir Audio: a newly launched, high-end custom IEM company. Some of you may recall HeadFi user FullCircle, aka The Wizard, posting pictures of his beautiful custom creations a while back. His real name is Dr. John Moulton and he’s a Doctor of Audiology. His...” --project86
“ Well this is my first (second I have the 8.A and I wrote this same review for the 8.A since I compared them both) review ever and I am doing it because it would be unfair of my part not to talk about this two excellent pieces of audio after THE EXCELLENT customer service I received from John, and I know some of you might get mad about this review since I am not going to focus just...” --Gorillaz

As always, Dr....” --Kunlun
“ Intro The first CIEM by JHAudio, the JH5Pro has been a long-existing audio option for those looking for a custom fit at a lower price. That being said, lower price isnt necessarily a good descriptor, as it starts at $400, and can easily go higher when custom graphics, custom cables, shipping, and rushes are added. In addition, a lower price entails a compromise in sound quality...” --grapefruit
We are proud to introduce the 3.A, as it presents an acoustic response with a little extra bump in the bass and good crisp highs. It was built for the audio enthusiasts that like fair amount of low frequency representation, coupled with good clean sound. The 3.A carries three precision balance armature drivers, one large one for bass production and two small ones for middle and high frequency...
Jerry Harvey's in-ear headphones are miniaturized works of innovative audio art. A perfect example of JHA's balanced armature sonic advantages is the 3-driver array found inside the JH 10X3 PRO. Exquisitely tuned crossovers deliver naturally balanced, seamless music reproduction and precise detail definition throughout all frequencies along with the kind of dynamic range extension...
