The worse kind of technology is one that promises things and then delivers only 80% of the time. It works enough that it gives you hope that it is usable, but when you need it the most it fails without any way knowing why. Also Bluetooth is a security nightmare, every few months there is some serious problem found and many of them are “by design” so cannot be fixed properly. It is also use for location tracking (beacon).

Wired headphones are like 100x cheaper, don’t require charging and will work for many years if you get one with good cable. There are only few failure modes that are easy to troubleshoot. But cable management can be a pain if you are not tidy.
