Well, it's not the OP's first time in bashing the HD650.
EXTREME/HARSH burn-in of Beyerdynamic DT 770 80ohm = dt770 80ohm>>>>>Sennheiser HD650. SHAME ON YOU HEAD-FI!!!!!!!!!!!!
i have zero brand loyalty, and always vote with wallet, ears and enjoyment.
i use the hd650 only when i need to be able to hear the door bell, or family members in the background.
true, the aurum cantus v3m could be considered bargain true high end, and being so, completely unfair to compare to these relatively cheap headphones. but i did think it would be interesting to reflect my genuine personal experiences.
