Sony MDR-S70AP Foldable On-Ears for $20

The Sony MDR-S70AP foldable on-ears, in the white-brown color scheme, are currently going for $20 by a marketplace seller with the order fulfilled by Amazon so they are Prime eligible. Not a lot of information is available on these. They might be a Japan-only product that found its way to an Amazon warehouse.

PS: the earpads remind me of the “telephone receiver” style, eg in Shure SRH 144/145.
