The HE500's are very heavy and I could not deal with them from a comfort standpoint. The 407 is lighter and more comfortable with either ear pad but it is no HD800 or T1 in the comfort department. I own the T1's and I can forget I am wearing headphones with them on. You won't be forgetting the 407/507.
407/507 are very true to amp/source too,
& they improve significantly after break-in, I was disappointed by the fresh 507,
now I use them everyday,because they are so transparent,never distract me from music.
the lambda signature have better mids, but Im not totally satisfied with their highs & basses.
