What it comes down to is this: check your attitude at the door. Especially considering the subjective nature of our hobby. What makes a person like DT880's more than HD650's? Or even stranger still, HD600's over HD650's? It all comes down to preference. If someone likes Bose headphones, I say, MORE POWER TO THEM! If someone is happy with their stock iPod earbuds and 128kbps encoded MP3's, I say, GREAT!
For me, it's about enjoying the music. If you can find enjoyment with your setup, that's awesome and really, that's all that matters (unless you're a sound engineer or something along those lines who requires something specific for a specific application).
Just relax and enjoy yourself. Don't worry about how much better your rig is compared to someone else, what would be the point of that?
