my answer still applies. the moremes are good both for tracking and for monitoring ... the sennheiser's are more 'hi-fi' i.e. enhanced bass and more leak. but they look nice, if that makes a difference to you. their main flaw is their extremely thin wire which last about a fortnight of being trampled on etc.
I suggest you go to www.head-fi.com it's all forums and everyone there is a bunch of headphone freaks. Any headphone q's are best answered there for sure.
