hmm, interesting, I find that it is impossible for me to go back to closed-back unless it is for portable use.
I really miss the open more spacious soundstage and the airiness when that happens.
hv you heard the C Flow?
Unfortunately not... Forgot to add that the Ether Cs are insanely good for music production. The high end is a tad rolled off which is apparent when checking the mix with HD600s or JBL LSR305 but other than that absolutely fantastic in terms of detail and neutrality. Can really hear every little tweak and thing that's going on.
