I paid $65. for these, and thought they sounded as good or better than headphones I've heard that cost twice that.  Now, you can get them on Amazon for $50., which makes them a great deal.  One warning -- as these are over the ear headphones, glasses can become uncomfortable to wear with them for a long time.  When they start to bother me, I just pull them up above the earpads.  It doesn't seem to effect my ability to read, which is all I use glasses for.  Anyway, if you are looking for headphones with a lot of soundstage, that can thump on the bass, and that won't hurt your pocketbook,  you are looking for these.  When the price went down, I ordered another pair for my girlfriend.  At that price, it didn't hurt at all.  Sennheiser makes great headphones in general, and these are about the cheapest audiophile quality headphones you are going to find anywhere.  I do boost the midrange a little on my pc, to give them a little extra punch, and after I do, it's like aural candy listening to stuff that really tests them, like classical or modern electronic.  But I'm mostly a classic rock sort of guy.  Pink Floyd Echoes and CCR sound amazing.  Just listened to Big Brother & The Holding Co. live, and it sounded like you were there.  What more could you ask for in moderately priced headphones?
