This kind of discussion isn't all that useful without providing history for comparison. In order of use: The Sony MDR-V150 was the earliest pair I can still put a name to and I wasn't dissatisfied with them, but they fell apart long before one of the speakers failed. Grado SR-60s were Head-Fi's budget quality darlings, but they hurt my ears with extended use and the highs were pretty fatiguing. Rolled with the Koss PortaPro for a while, which sounded excellent for the price range despite being built for portability, but those are even more uncomfortable. I got a modded Fostex T50RP next, which sounded great but requires a decent amp ($100+). The Shure SRH840 had an equivalent sound quality without an amp and a much more convenient design- my favorites so far. Using the Audio-Technica ATH-M50 now, which sounds a little less detailed than the SRH840.
I got the Fostex and Shure cans used on ebay for ~$70, but they're hella expensive now. I feel stupid for paying twice as much for the ATH-M50 (they were store-bought), but they go for $60-80 online. Plenty on eBay, they're like one rung below Dre Beats in popularity right now I think. I'd definitely recommend the PortaPros if you don't mind sore ears.
Disclaimer: Using a Xonar Essence XT right now, which is supposed to be a top tier DAC but needs the on-board equalization to come even close to sounding neutral and/or
decent for some reason- could be that the card is damaged, or it might be the headphones, but basically don't quote me on the ATH-M50s. I've never been able to distinguish 192 kbps mp3s and FLAC so maybe my ears suck
