The Bass of the d600's is pretty nice but that's about it. The looks going from the beautiful D5000's
To some upgraded version of the Beats or Sol, or what ever other horrible Celebrity endorsed headphone was a huge mistake on their part. Not to mention they forgot to work on the rest of the sound spectrum (Just like those other brands) so that also is a major fail on their part. Hopefully next time they'll remember what made them famous and go back to quality cans that have the total wow factor from build, looks and most importantly sound.
To be honest, I should thank them. The value of my Denons shot way up after all the bad reviews came out. Stinks because I was wanting to find a decent used pair of D2000's but now they are selling for more used than they sold for new!
Bitter sweet I guess
Just a shame you're using such a good headphone from a FiiO E11...
