Arent these the Custom One rebranded?
I was a fan of these for a minute but I checked them out next to the DT770 (flat with a 4k notch) and DT990 (v shaped repsonse) and they are not as good as those. These are cans for teens.

I can't argue the demographic Beyer targeted with their release of the Custom One and Custom One Pro

but you're mistaken if you even consider Beyerdynamic would just 'rebrand' these cans, slap the word studio on there and call it a day.
The frequency response graphs look identical, but I've tried both (own the Custom Studio) and I promise you there will have been a lot of driver tuning because these two sound nothing alike. The COP is basically only usable completely closed and perhaps with one bass port open. I say this as a person who really likes bass (planar bass mostly). Sliding the bass ports even further open will result in a completely muddy mess where I can't even start to comprehend what music you must listen to think this is somehow an enhancement.
The Custom Studio on the other hand is as neutral you'll ever find a headphone. Even with all the bass ports open, it's not bassier than let's say a HD650 ? It's punchy, you'll hear it but you will never feel it.
