I paid $100 dollars for my Grados, for that price range, they are great. Very comfortable on my head. Near perfect amount of bass for my preference.
I also have some HD 280 pro's which are great except sometimes they feel like a vice on my head and have a lot more bass.
I have some pc161's for gaming. They are decent sound quality imo with a great mic(at least that's what i'm told on voice coms) although I'm thinking of trying something different.
I've driven them all with an m-audio firewire 410, a profire 610, a go-vibe and various mp3 players, phones, and pc's throughout the years. Although currently I'm just using a xonar DG which actually has a decent headphone amp built in and the simulated surround sound software is fun to play with because you can move each virtual speaker around the "room" just by dragging and dropping.
I've been trying sub $150 dollar headphones for a long time. These are just the ones I prefer. I don't rely on other people to tell me what sounds good. That would just be ridiculous.
