I'd like to confirm the different iterations of the HD650. Is the latest (and greatest?) one the silver screen driver? This is the one that supposedly has better treble (less veiled) correct?
And it is easy to tell just by looking at the outside of the headphone into the grill right? If you see white/silver (as opposed to the earlier black), then it is the newer version.
Has there just been the two - black and silver/white?
Yes the Silver mesh is the latest.
Yes its easy to see looking through the earcup perf.
My understanding is that there have only been two mesh types... the older matte black and the current silver one. The various forms of white mesh baffles were used on the 580/600 and never made their way onto the 650.
