Excerpt: Because these earphones will look familiar to some people, it’s worth mentioning a few details about their heritage, particularly given that the JH Audio name mightn’t initially ring a bell. JH Audio is a relatively young earphone manufacturer started by industry veteran and Ultimate Ears founder Jerry Harvey, who is now competing directly with the custom-fit division of his former company.
Conclusion: For reference, my iPhone 3G has an output impedance of 3.1 ohms across the band; my iPod Classic 160GB's output impedance varies from 6 ohms at 20Hz to 4.5 ohms at 1kHz and 5 ohms at 20kHz. Using the iPod Classic will shelve the JH16's low frequencies down by about 1.5dB compared with the level at 1kHz. By contrast, the Ray Samuels headphone amp, which has a source impedance of <0.5 ohm, will give the same SPL at 20Hz as it does at 1kHz.

Excerpt: In the world of high-end, high-accuracy in-ear monitors, Jerry Harvey is regarded as a both a pioneer and as a bit of a legend. Harvey’s work in this area began at Ultimate Ears—a company that he helped found and for which he created a number of custom-fit in-ear headphone designs that have come to be regarded as classics by the performance-minded musicians and audiophiles who know and love them.
Conclusion: Only Jerry Harvey, the founder of Ultimate Ears, would know how to match his former company (and primary competition) so perfectly. JH Audio's JH16 Pro custom-molded earphones sound sublime, but just like the competition, they cost a small fortune.
