I'm not familiar with the details of which exact pads are used on the various models, I do know someone earlier showed this link (
https://forum.headphones.com/t/hifiman-he6-official-thread/12784 ) where I got the V2 measurement from (look further down the page at that link) and the measurements at the link is showing an HE6 (
not SE) with Velour pads vs an SE V1 with stock pads vs finally the stock SE V2. The first measurement (HE6
not se) with velour pads does look quite close to the stock V2, but don't know what conclusions you can really draw as they're 3 different models of headphones and the stock HE6 doesn't match the HE6se:

Ah, you've got the V2 haven't you, did you try my EQ I posted earlier? If I remember rightly you tend to start of with an Oratory Harman EQ and then tweak it to your preference......my EQ would be relatively similar to an Oratory EQ given that it's hugging the Harman Curve, but obviously it's not gone through the Oratory measurement process so the methodologies for the creation of the measurements will be different between Headphones.com and Oratory even if they do indeed both use a GRAS rig (so that's one variable of difference).
