Another update regarding AT!
Saw many people uses it while commuting. Seems like their preference would include IEM, and some big-sized cans. Spotted quite a few CK/CKM series users, one or two Buttons, and surprisingly, a girl on a monitoring series (can't remember the model, seems like DJ series). it is OK to wear a medium-sized headphone around, but i haven't seen anyone with a full-size can yet.
Checked the price at BicCamera, Ikebukuro. Eyed ATH-ES7 at 14,800 yen. Also saw the noise-cancelling ATH (forgotten which model), itchy.....

Also spotted the flagship W1k, W5k, A2k etc on sale. Didn't check the price coz i know i cannot afford one for now lol.
From the on-spot trying, I liked AD900 than W1k though. i'm sure it won't be disappointing if it's paired up with proper gears.
i'll post some pics next time....
ES7 is cheap in Japan market and also one of best portable. Noise-cancelling Japan has two type (ANC7 is full can size and ANC3 is a IEM Size). AD900 is well know easy drive cans but W1000 is very hard to drive if you don have a proper amp on it.. Currently my Class A amp will be upgraded to another level which is using Monoblock like a hifi gear...
