Further update:
I've tried them out with a variety of tips including Sony Hybrid and AT silicons and found the Comply TX 400s to be quite nice. They do an excellent job of isolating and keeping the weighty FADs in my ear which has made them solid on the go (much superior to my DDMs but inferior to my SE530s for pure isolation).
Soundwise the FADs continue to impress. While their presentation is a bit forward and bright, I am really finding that to be to my liking. Their Soundstage is absolutely astounding as well. As I said before, a simple pairing with my Fioo E5 really opens them up when listening at home. On the go they pair just fine with my ipod/ipad and their extremely high sensitivity makes them easy to drive despite a bit of hiss.
The cord, despite its long length, is fantastic and nearly tangle-free as well.
But the most interesting trial my nearly-priceless wonders have gone through is the "girlfriend test."
A week or two ago I let it drop to my gf how much my FADs cost and she nearly had a heart attack. My gf is very conservative with her money (the opposite of me) so I wasn't surprised at all at her reaction. Her first response was "I didn't know earphones could cost so much!" She immediately wanted me to check on the return policy, which I did!
Half-serious, I asked her to try them out, saying she would be able to tell the difference. After a ten minute or so A/B/C with my DDMs and 530s she started laughing.
"I like them" she said "but the price is ridiculous!" she did add that they all sounded a lot better than her Sony Earbuds!
I told her I had been initially been planning to get the Ortofon EQ-7's at about a third of the price. She suggested that maybe I should do a return/exchange. She called the shop to check on the return and said I could have another week with my FADs and think what I wanted to do.
So just this past weekend I went out to meet my gf near Akiba, where I purchased my FADs. By this point I was actually considering to return them, as I had enjoyed them quite a bit, but I was thinking about everything I could do with that 98,000yen back!
Well, while we were on a fairly long train detour, I did another A/B session with my gf as we were both listening to music on on Ipods. While she was listening to Queen I alternated her Sony earbuds/DDMs/and the FADs.
To be honest, I was really expecting the quite spectacular DDMs to perform well enough to further turn my gf against my pricey FADs. In fact, I had already been pushing the DDMs as "the best value in earphones" which to her was still "too expensive" at 15,000yen.
But, to my surprise, just as I was planning to return them, my gf announced "you should keep them!"
My response "Do you really think they are worth it?" I pointed at my DDMs "They sound pretty good for a lot less, don't they?"
"But they aren't comfortable and they sound too loud." I wasn't sure what she meant but after a little more discussion I think she found their timbre and bass to be blocking detail...
I tried pushing the DDMs a bit more but she actually became insistent! And I decided I really wanted to keep my FADs anyway so I gave up
Then today, we were in my apartment listening to music, and she wanted to listen to my FADs some more. I asked her to take a look at a Japanese review of the FADs where they were compared to the 530s. So I pulled out my 530s and had her do a little more A/B. To my slight surprise she criticized the 530s for being "quiet" which I believe with more discussion was a complaint about their more laid-back sound. She also added that the FADs sounded to her "like a concert" which I told her was called soundstage.
I joked to her if she was thinking to buy her own pair of FADs but she gave me a look like she expects me to give her mine! Which I certainly won't
But anyways, it's good to know the FADs passed the "girlfriend test". I guess I can sleep more comfortably now
