Things to note:
I live in Indonesia, So, if possible major brands, amazon discount doesn't apply either.
I don't want worldwide shipping either, if it hit the custom, I'm dead.
Seller in IND usually, their price is +$4-$7.
So, anything else to mention?
(sorry, i've posted this too much)
Sounds like you only want to buy local. Unless you can show us what models of each brand the stores in your city sell, we can't really help you.
Are there any local headphone forums where you live?
