How many headphones do you have?

[Danneq]

I try to not get too caught up in buying expensive headphones, but I admit that it is almost too tempting after reading reviews at places like this one and Head-fi.

I mainly focus on earbuds and (open/semi open) headphones. Right now I have:
AKG K420
Sennheiser PX100
Yuin PK3
Sennheiser MX360 (back up in case the PK3 die. However, the sound quality they produce is not that great...)

I am looking at Yuin PK2 and G2, and also AKG K518 for my wife so that she gets some bass heavy phones to satisfy her portable bass needs.

This year I live in Machida, southwest of Tokyo, in Japan and apparently Audio Technica`s main office is situated here. I am curious about the ATH ES7 and ESW9, but sadly living in the same town as the main office of ATH doesn't make them cheaper...
