I'm generally doing a lot of movement while wearing headphones, whether it's walking, working, or cycling, so I've found wireless headphones have lasted much longer than my old wired ones as well as being more convenient.
Wired headphones do have a bunch of advantages, but so do wireless, and product lifetime isn't a great measurement when it's dependent on use.

edit: A better example would be smartphones, with support for models being dropped within a few years, and them slowly becoming more and more incompatible with new features, regardless of their physical condition.
