johnvonmacz,
I have a set of Sennheiser HD 558 and am really happy with them. I primarily use them for Pandora and YouTube. For me, the sound is excellent. They do a really good job hitting all frequency ranges. As a side note, they are not noise cancelling headphones so any outside noise could interfere with your experience. They are built really well taking away that feeling of breaking easily like many other plastic headphones.
They're available on Amazon.com right now for $146.45. You might be able to do some shopping around and find them any cheaper.
Let me know what you end up going with.
Cheers!
