From my last trip to Yodobashi superstore in Tokyo:
On every trip, we allocate an entire afternoon to tour all the floors of the new store. You think you have died and gone to heaven. You can combine every Bestbuy and Fry's in US and they would have as much stock of electronics than this one single store has! We are talking infinite number of anything... Cameras, phones, dark room equipment, computers, appliances... I counted the inventor in a tiny little area that stocked flash memory. We are talking a 10 foot by 5 foot area on the wall. Are you sitting down? $250K worth of high-performance flash memory for high-end cameras!
Anyway, you see how many headphones they have. It is a messy section unlike the rest of the but boy, does it satisfy your need to test any and all headphones you want.
