oh you jumped on THAT DEAL that deal was insane!!! i'm still shaking my head on how that deal happened!
anyway i probably don't listen to my music longer than 1-1.5 hour at a time soo it should be okay
the re0s good choice! i own the re400s but sometimes i find them not bassy enough for the commuting purposes which is what lead me to the m80s (which is fairly neutral) but still bassy =)
Yup was lucky to find a pair in my area. I like the M-80s cause of the bass while the RE-0s are good for a more neutral sound. I just upgraded to the dn-1000 to get a wider soundstage and a bit more bass. I will still use my M-80s for my shorter listening spans and if you they are comfortable on you then they will work out well.
