I've refrained from commenting as I can't eloquently explain/talk about why everyone finds these people's experiences so "polarizing" but you seemed to do the job decently.
People are seriously expecting things that were never promised, said, or mentioned by Sennheiser/MD so it's kind of driving me up a wall. The sound signature is right here for everyone to see, confirmed by multiple sources, but people are expecting to hear... Something else? It's very odd and humorous in a way. These have less mid bass bloat than my 598, the 650, etc, but people somehow call these "dark" and many expected (before we were getting pairs in hand) were saying these were going to be dark/bass cannons... Because of bass extension with minima mid bass bloat.
People are odd. And it's confusing how everyone's expecting to base their opinions off of what other people are saying here, and are letting people's words bias their feelings a little too much.. People can hear different things and should talk about it, but for the love of god I'd love if people would just stop saying "this is so polarizing" and taking everyone's opinion as fact LOL.
There's great bass extension, and uncharacteristic (for sennheiser) treble roll-off. People should be able to guess if they like that sounf signature based on other HP they own and stop expecting miracles..
Also, so many people have clearly not read anything about these HP because there are constant questions about the drivers and other parts of these that have been answered and are clearly visible on the drop page. Oi vey.
/end rant
Tldr; just wait to get your pair and stop listening to everyone who is expecting impossibilities from these HP.
