Aha... so now that it comes to wired, the "how are you supposed to know" doesn't apply anymore?
You bought a shitty wireless and use that to hate on the entire protocol.
I've bought bad wired ones where the wire breaks easily, but the same logic doesn't seem to apply there for you.
Any decent wired headset has easily replaceable cables?
Any decent wireless won't have the problems you've mentioned. And the battery is not going to be a problem for many many years. My boss ones are on their fourth year. Still get out 7-8 hours of non stop usage which is more than enough for me.
But sure. They do degrade. That's factually true and inevitable. It's part of the price for the convenience of not having to deal with a cable.
But you hit the nail on the head yourself. "Any decent headset". Same thing can be applied to wired, as wireless. Buy decent products and you won't have issues.
"How are you supposed to know" goes for both too. You can't tailor your argument to only work for one type and ignore it for the other.
