Thanks to the people who post changes in direct comparisons to a control headphone before and after burn it.. for example HD650 vs other HD650 or even HD650 vs. Other headphone,
this is part of the scientific method.
I got my HD650 yesterday used. i compared them with my senn HD430 from the 1980's (600ohms and similar sound signature) and my AKG K702 (older one with lean bass).
out of the three i liked the HD430 best, the AKG K702 second and the HD650 last. not because of sound signature , but because of sound quality.
like other previous posters, i also found the HD650 sound to be lumped together in the high bass and low mids., cluttered in the middle, like a cheap headphone..
i just thought it was the sound signature of the headphone until i read this thread and found others heard the same thing before they burned them in.
but the reason i liked the HD430 and AKG K702 better was because right now they have a more integrated sound that is smoother and sweeter.
Its as if on the HD650 some of the harmonics of the sound were not connected to the fundamental of the same sound. harshness, rough edges , especially on the attack.
in other words, harmonics are coming off as distortion, or the harmonics are distorting to be more direct about it.
thinking they sounded like they needed burning in, i asked the seller if they had had much use and he said he hardly used them.
so my HD650 were on pink noise all last night and morning and in the 12 hours since then some Saxophone Jazz music all day
in any case i will continue to use pink, and some brown noise and a variety of music types .
I'm hoping to find that these cans will turn into the gold standard of studio reference headphones that everyone swears by, the end game headphone that is fatigue free, natural, detailed in the midrange with the relaxed treble.
I will post how things turn out . i will be comparing them with my HD430 and K702 again. i hope the harshness goes away .
