Like ostewart said - you should have done your research properly before buying them. they are phenomenal cans. the clarity and detailing in mids and highs is not something you see in headphones under 100$. they are as good as 200-300$ cans. your music taste requires more bass and these are bass light. you mentioned - you read reviews before making your decision. i can't believe you missed that they were bass light. almost every review screams about it . these cans are mainly made for rock and acoustic music. so it's not the phones fault , it's yours. you should have done your research well. i hate to see you rating them 3 stars. it's an insult to the cans and to us grado men. please take your review down or rate them higher if possible

It seems a bit odd writing a fairly negative review if you didn't research what the headphones sounded like before you purchased them, it would have saved you time and money.
I personally enjoy the slightly brighter sound of the SR60, I have started to modify mine too, and they are no longer bass light.
