I'm not sure how to reconcile your two "wants" here. A battery and a current bluetooth chip are required for any pair of headphones to function wirelessly, no matter what. Bluetooth has been pretty good about keeping backwards compatibility, so I wouldn't worry about these becoming unusable when a new version of the BT spec comes out.
If you don't actually "want" a pair of wireless headphones, then the AirPods Max aren't targeting you at all. Absolutely nobody should buy these if they don't intend to use them in wireless mode, there are better wired headphones available for less money.
I’m not sure you “want” to understand me. I treat them as __headphones__ and simply stated that it was a shame that (esp. expensive) headphones which used to hold up for a long time are now worthless after a few years. That’s it.
