I love looking at those pics.. looks like a fun place! So want to go to Japan .. there's no where in Australia like that. Can't try much here other than the AudioTechnica store in the city of sydney and the apple stores.
I was also surprised that hong kong is like that too ... went there last holidays and there are quite a few shops where you can try them to your heart's content. I went to a store in mongkok (hong kong) that had the best customer service and they will take a bunch of headphones that you choose and give you a big table and you can bring your portable amp or what ever and just try them as long as you want. They also had a very wide range to choose from. Will be going at the end of the year again .. will definitely try to get some pictures.
Was this place in Mongkok Jaben by any chance?
If so Melbourne will have our own store by the end of the year, give us a visit sometime!
