Thank you for your answers : )
So I think SR60 would be better for me.
I know that Grado headphones are not available in my country :( (but I wish to have it)
I should buy it by shipping by amazon.com so I should pay extra money. So : I can't test something, I should buy it and its probable accessories only ONCE!
I've heard SR60 is somehow uncomfortable, but it can get better by buying some pads/cushions.
I want to buy cushions/pads for sr60 to be its most comfortable and best sound quality.
Which types of pads or cushions do you suggest for SR60 ?
(Honestly I don't know the difference between cushion and pad (perhaps because my English!), I want the best thing that I can change this on-ear headphone to over-ear one)
Would you recommend its best to me? (something in Amazon)
