this is too expensive for a closed back, when i could buy a hyperx cloud alpha for 49 bucks and get ~80% of the sound quality.
$350 for something that has the same build quality of a 560s, its insane.

IMO Hypercloud X is a very colored set, it's worth paying a little extra for AKG K371 och an Shure SRH440 non-A.
I thought it was improved even though it looks like the 5 series.
Looks like it has too much clamp for me.

The build quality is significantly better (metal headband, for example).
Also, the cost aspect is going to be true for all headphones. 80% of the sound quality isn’t even much, you might as well buy the KSC 75 which does probably 80% of even high end headphones and costs about 30 bucks. People buy expensive headphones because they chase those last few percent (or even permille), and that doesn’t automatically make them a bad deal.

I probably haven't heard such a stupid statement in my life. Clear you have little to non experience with high quality headphones, in special with closed headphones.
Mind you these are indeed arguably not good value for the money compared to other headphones. Though I probably wouldn't pick hyperx cloud alpha as an example. HD620s are mass produced by a large company. I bought a set of Austrian Audio cans for a good amount but still less than these I think. Though I think the Austrian Audio cans likely have better materials and quality. Personally I would like to support smaller companies if possible. At the same time KPH40 is my most used headphone by far.
Bear in mind that Sennheiser Headphones are often sold well below the RRP it may be that once a few months have passed they will be a considered better value for money. I think if the price drops to somewhere in the £200 - £250 bracket they will be worth getting.

I lowered the clamping force to more pleasant values (3N).
extended the sliders, but it on a stack of books that stretches the headband (no pads), don't over-stretch too much.
Then, using a hair dryer slowly warmed up the middle part of the headband (not too hot, you don't want to melt the plastic) for 5 mins or so.
Then let it cool off for 10 mins before taking the headphones off. Put the pads back on and check the clamping force again.
Better to repeat the procedure with a bit more stretching than to ruin the headband.
As seal is paramount on this headphone don't make the clamping force too low otherwise seal will become an issue.

So what does the HD600’s measurements look like?
A reminder.
So that’s excellent, except it’s around 10db down at 20hz, and there’s a small hump of around 2.5dB at 200hz.
And the graph comparing that to this new model…

and on another fixture HD600 vs HD620S:
What do you think the clamp of a K371 would be in comparison? Maybe I'll get to demo these at some point as the tuning looks like it might be something I am interested in.

K371 clamp is a little lower.
Compared to the modded 620S or stock?

I saw you copied my spec sheet (which is fine) but decided to go for the sensitivity and efficiency ratings published by Sennheiser on the box.
They are incorrect and have corrected their numbers on their product page.
Don't know if Sennheiser also fixed the error on their boxes but they did on the product page.
Sensitivity is in dB/V
Efficiency is in dB/mW
And yes, these headphones are very good.

The (average) sensitivity is actually a bit higher than it is at 1kHz exactly because of the weird dip it has just above 900Hz.

I needed about five minutes of listening before I pulled the trigger. Very nice indeed and without any EQ.
What I picked immediately were what reviewers have said: lot's of tight, slammy bass, big soundstage. The build quality feels very good and solid in my hands. For my head the seal is airtight, clamp force is maybe the tiniest bit too hard. Only problem is that with current temperatures my ears get sweaty almost immediately.
If I had to guess, I think Sennheiser has a big hit here and a headphone to beat in it's price range and above if you need a closed back.
