Pros: Excellent sound for the price.
Cons: Bass is slightly lacking but is present.
I happened to get these cans for $55 at that price I'd say they're well worth it. I preformed the foam mod about 10 minutes ago and, yes, I certainly noticed a difference. They've opened up a bit. My $55 purchase just became a greater value.
This is my first pair of audiophile headphones, and, unfortunately for my bank account, not the last.
put simply, if you're on a budget and need some good cans at a good price, these will be your huckleberry.
