I just got a March 2023 shipment of the HD 6xx and it did not come with anything other than an attached cable and was shipped in a box as shown above.

The sound is amazing for what I paid for them. Do I have to order a storage case for them? Yep. But I can get one on Amazon for 20.00 which is fine.

I also picked up the 660s over the holidays and it did come in a hard shell box. Those headphones are simply stunning. I love them.

Being a bit of a headphone "junkie", most of the headphones I get come with a cloth bag at best. My Audeze came in a bulletproof case (well, it feels like it) but those were on the expensive side and I would expect that.

I'm okay with the way most of the headphones come. If I have to pick-up a case, so be it.
