“ http://www.head-fi.org/forum/thread/524282/review-unique-melody-miracle-6-driver-custom-iem That's my full review. In summary: These are simply the best customs, and possibly the best headphones of any type, that I have ever heard. I prefer it to my JH13pro due to it's better deep bass response and more natural tone. These sound great paired with a simple portable...” --project86
“ I wonder why UERM is often disregarded while picking from $1000 range. I'm guessing that it's due to "only" having 3 drivers, versus having 8 drivers per side. I can say with confidence that driver number does not equal sound quality. Another reason I see why UERM might not be picked is its sound sig. It's perfectly flat. Personally, I love this. Here is my break down: UERM is...” --kimvictor
“ 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
“ 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
“ Ladies and gentlemen say hello to the Tralucent Audio 1Plus2 hybrid IEM. This little gem of an earphone easily falls into the group of pricey high-end mobile audio gear with its suggested MSRP of 1300 USD. On first glance this rather plain Jane piece of gear with its beefy silver cable may not look like much but you only have to give it a few minutes of listening time to realize...” --DigitalFreak
“ The price paid is because I had to do rushed-rush processing. 1964 delivered, with the best customer service imaginable. The Q has great lows, very good mids, but lack a little in the highs. I like heavily colored headphones and I knew the Q was a reference monitor going in...but that didn't keep me from being a bit disappointed by the lack of excitement to their...” --benzoylmethyl
“ 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
“ Paid about US$1200, including custom fit, and am overseas. A very highly detailed and balanced IEM. I have an iPod only filled with audiophile grade music. Put in anything else, and you hear warts and all of lesser recordings. I use this with my portable set up, which is played through the CypherLabs DAC and the Go-Vibe Porta Tube amplifier. Cables are ALO but I really did not...” --Stephen L
“ This is my very first pair of custom IEMs after trying almost all of the high end universal IEMs -- SE530, UE Super Fi 10, Etymotics etc. The sound of these UE11 Pros is superior in every way to all of the universal ones I had, but even more important they stay in my ear and provide a proper seal. Since my ear canals get very narrow, I found it very difficult to get any of my universals to...” --alyanm
“ I've taken down my review of the Merlins and will repost it once I get them back. By now it's been 4 months and I've had them in my posession for no more than two weeks out of those 4 months. Two weeks into the 3-5 week estimated turnaround time for my remolds/fixing and UM have gone back to maintaining radio silence. Not a word, not a single peep, no replies to emails....” --Sorensiim
