I think that people are just assuming the worst case for wireless and best case for wired (in terms of longevity). AFAIK most wired headphones don’t have a replaceable cable, and the ones that do tend to be pricier. Personally I’ve had the same AirPods for 3 years now, and the batteries seem fine. The only pair of wired headphones that I’ve had last that long were $400 sennheisers, and I think I’m pretty careful about making sure that cable ends dog get bent and that the cables aren’t tangled.
