I worked as a techie at a radio station for some years. We maintained (repaired on site) around ~20 pairs of professional headphones for studio usage, used by many hundreds of members of the station. Some of these headphones lifetime definitely exceeded a decade even with heavy use, requiring minor repairs e.g. cables and jacks. Personally, I used one pair of ath-m50x's for about ten years. I just replaced it with some Beyerdynamic's, which I expect to also last at least ten years. All of the Bluetooth headphones and speakers I've bought have lasted less than a few years. Half the time the batteries fail (and often aren't user-replaceable), the other half it's some component I'm unable to diagnose myself.
