Look like pos angled beyer pads that don’t belong on a set of beyers. Return em, first chance you get or, if you don’t want to deal with the hassle, use em as a dog toy.
Please ignore DeeDrick. If you find these pads comfortable then that’s all you need.
As for headphones, the beyer DT770 250ohm might do well. The DT1770 might also be good. I personally use a very similar non-perforated pad on my TR-X00 PH.
If it fits, it sits. I use a similar non-perforated pad on my own beyer DT770 250ohm and its sound better in my opinion. Less sharp highs and maybe a better sound stage.
One heart for supporting local businesses but I doubt those pads would be good for anything that better Earpad manufacturers haven’t already done better. Perhaps you can use em for baseball practice
