Software, batteries, and the bluetooth comm protocol are three giant points of failure. An example, I can no longer use my car's (2012) bluetooth with any modern device. At least, it is horribally laggy and doesn't display data, when it works.

Points of failure on wired buds are the cord and connector construction and materials. So you can generally know the "more you spend", it's likely being put into the construction (for reputable brands).
