Pros: sound quality, design, easily mod'able
Cons: design,price in Europe, soundstage
I had SR225, MS1i & this SR60i
In Europe, MS1i probably have the best ratio price/performance but still they are not Grado.
I love its unique vintage design even though it looks cheap.
Grado sr60i are very good sounding, to me they are perfect for rock/metal music but not only.
They are comfortable , light,but soundstage is very small for such an open headphones.
SR225 was better but was not night & day versus SR60i so price difference in Europe is not justified.
Newcomers, I would advice you to buy Grado 2nd hands here on Head fi, you'll get a SR225i for the price of a 80i new or 325i for the price of a SR125i in Europe.
Grado's are unique and I think everyone should have one in its collection
