My wired cheap phones that I used almost daily for online meetings and calls is 11 yo, and still works normally. I doubt a cheap wireless would be close to last that much. I don't even treat it with obsessive care or anything.

I still have an old Archos Jukebox that runs off weird green Double As and a hard drive. Everything else, including the screen, needed replacing before the aux jack had even an inkling of a problem.
