Am I crazy for considering buying a second HD650?

The HD650 has been my favorite headphone for 10+ years, and I still have my original pair with the older design.

In 2019ish Sennheiser made some slight cosmetic changes and I kinda wanna buy it so I can have both versions. Lol

Obviously I don’t expect them to sound different but I just want both designs in my collection.

Does anyone here own multiple versions of essentially the same headphone? If so, what was your justification?

Also, when are we getting an HD650 anniversary edition?! It’s past time!
