According to this reviewer who owned both a pair of HD-555s and HD-415s, the difference is night and day (the 555s are obviously the better of the two... as they cost more).

HD-555s on Amazon. Right about the price you were looking at.

Again though, I feel I should tell you about the downsides. 6' cord. Pretty big and may look "goofy" if you're self-conscious about this sort of thing (what I'm saying is that they stand out a lot more than - say - iPod earbuds). They leak sound if you have it nice and loud - people WILL hear your music at even moderately high volumes. They aren't noise-cancelling so you can hear people around you. I don't know if those 415s have these issues.

thanks but its really not a big deal. the only reason i wrote that as my price range was because i don't think I could bring myself to suddenly spend 4x more on headphones than I had every previously paid without knowing for sure that I will be satisfied with my purchase. spending $50 extra isn't going to kill me, but I will definitely hate myself more if I pay $100 for headphones that I ultimately decide are too uncomfortable for everyday use than if I spend $50.

Return them yah yeah but it's a hassle and i'm lazy, especially if it's online ordering.

I don't know if it's a good idea to ease myself up the audophile ladder (heh) like this but unless I get unanimous agreement that there is a huge difference between $50 sennheiser and $100 sennheiser, i will probably not bother to spend twice as much.



edit: hmm well i didn't realize mama luigi was comparing his headphones to the ones headphones ​) posted. Still, leaning towards the cheaper ones right now. Thanks for the pro-tips dudes
