There is a market for 2nd hand fitear customs in japan. E earphones do sell 2nd hand customs. I myself offered to buy jeremy Shu Shu's custom 435. When he refused to sell, I pulled the trigger shortly afterwards. I don't see how mh 334 is a blind alternative to tg 334 because suyama himself mentioned that the tg 334 is in fact the universal of mh 334. I do agree that they sound different though. When I compared my tg 334 and mh 334 side by side, mh 334 sounds more realistic, more controlled as compared to tg 334. Sound stage is also noticeably wider than tg 334. In sg the wait time for tg 334 is roughly 1 year vs 3 to 6 months for mh 334, 2.2k vs 2.7k. A thing to note that most tg 334's in sg are no longer covered under warranty/ warranty ending soon. From my perspective, if I were to buy such an expensive iem, I would need some form of reassurance from the local distributor. No doubt the common argument is: fitear's build quality is the best among all iems,but then again you couldn't exclude Murphy's law as none of us can be 100% sure that the 2nd hand tg 334 is going to function well. Likewise, just as fitear customs couldn't be reshelled, tg 334 isn't meant to be reshelled as well.
