Wow, I became really confused from all of these comments.
Look, I got about 1100$ from summer work (last summer).
I work in the summer in order to buy something that I like, in order to "treat" myself.
I don't really need to save money for emergency, my parents do their job very well.
So, when I do earn money, I want to buy a high-quality product with it, something useful.
You keep offering me 100$, 200$ headphones, and I know they are good, but I want to utilize the money for a really good product.
At first I wanted to buy a Canon Vixia HF S10 camcorder, but for some reason I forgot about it.
Now, I don't have an amp and I don't want to have one, it cancels the whole portability idea.
So, please tell me, do you know if the ATH-ESW10's work well without an amp?
And as for sound isolation- if the quality of the ATH-ESW10's is really good, I don't really care about isolation.
I mean, people call them portable headphones, so they probably have some level of isolation, am I wrong?
Edit: I found ATH-ESW10 on ebay:
Audio Technica ATH-ESW10 Headphone Headset ATH-ESW10JPN - eBay (item 300344753312 end time Oct-03-09 21:06:06 PDT)
It's pretty expensive.. I read comments of people who paid 480-500$ (before shipping),
It's probably because it's a limited edition.
