I would love to see some pictures of insides of The headphones. Especially since the impressions are polarized about The bass.
Small differences in build can Make a great difference in sound. If there is something blocking holes on the Back of The driver it can kill the bass. Excessive glue etc. And maybe there have been some minor production change that are not mentioned. Even If there is thicker paper on drivers vent holes can have a drastic change on how The driver "breathes" which has a huge effect on bass performance.
I would get a pair to find out myself but I'm moving in less than two months so I can't risk having headphones delivered to a wrong address.
