“ 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
“Here's my video review of the universal Roxanne, kindly loaned to me by Jerry Harvey. Notes: The tips I was using were given to me and are called SpinFit. I don't know of anyone selling them at present, but Jerry Harvey has said he is going to look into making them available. ” --Currawong
“ I feel obligated to share out-of-the-gate that I am no CIEM expert! As a matter of fact, I don't even particularly enjoy IEMs - I love over-ear or on-ear headphones. That said: Experiencing JH Audio's JH-13 Pro (now Freqphase) IEMs at Canjam 2009 was nothing short of a revelation for me. As a matter of fact, the experience was so far from anything I had to compare it with that I ended...” --mikemercer
“ 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
PK2 earphones are the low impedance version of PK1. Although not as good as PK1, PK2's sound signature is similar to PK1. You don't have to drive PK2 with an expensive head-amp. If you are looking for something with high performance/price ratio, PK2 might be the best choice.
“ These were my sweetest sounding head-gear yet. It would be brilliant all-rounder if it would not require a portable amp for portable use. This is the first reason i left it, otherwise i almost got an ear infection from those foams.., they get dirty in a few weeks of massive use. I recommend them to clean, i boiled them in water. ” --angevoi
“ Well firstly this is not a true iem. The sound is about as great as one could get from an earbud. In my limited experience and without trying the pk1, I would say these are the finest buds you can buy. With that said, these are not for everyone, this is a niche product within an already niche market. I find driving it with my D12 anaconda makes for a pleasurable sound,...” --Jamesdeandoa
Clearly, this is the worlds bestnbspclip-on ear-clipnbsptype headphone. Its a bit inefficient, so you might definitely want to consider a headphone amp, but the Yuin G1A is simply a terrific-sounding headphonenbspany way you slice itnbsp -- and even more so in this difficult category not known for sound quality.nbspClip-on headphones are always great if you dont want to muss your hair,nbspfor...

“ The PK3 is a great, warm earbud. It does vocals especially well because it is very mid-focused. It has impressive bass extension, not especially strong impact; the trebles are smooth and may roll off too soon for clarity and detail nuts. But the mids are what the PK3 are all about. ” --kmhaynes
