The use cases for many people have changed dramatically as well. I think if I was an audiophile, and used headphones primarily to lie on the bed smoking hash and listening to Steely Dan, I would share your concerns.

But I use headphones for two things: talking on the phone/listening to music when I walk my dogs or to pick up my kid, and for meetings at work (I'm long-term remote). Having cordless technology is nice for the former, where it replaced cheap wired earbuds that are always tangled in my pocket and never last for more than a year or so. It's critical for the second, so that I am not chained to my desk for the 1-2.5 hour meetings that I have multiple times a week. And I have to talk with my use cases, not just listen.

The heirloom-quality audiophile headphones are simply not workable for my use case, and I am sure that I am not alone here. And my father, who I am pretty sure did spend lots of time lying on the bed smoking hash and listening to Steely Dan, did not ever pass his headphones down to me.
