The Grado SR80i is one of the entry-level models in a legendary lineup. It is the first pair of proper cans I have owned. I'm a big fan of metal but being a student didn't have enough cash to burn on high-end stuff and after a bit of lurking found that cans were being recommened by many...
Pros: Aggressive mids, Tight lows
Cons: Isolation, Initial fatigue, Sometimes too bright, Cable
Summary: I have had it for a very long time. Smooth, rich sound. I use it exclusively with my iPhone and iPod nowadays.
The foam just ripped even though I gave it TLC! I wrote to the company and a received a snarky response from a smart-ass there - he must hate working there, or what.
Pros: Fabulous sound, but I use it only while trying to fall asleep
