The Sony WH-1000XM4 approach.
Taking them off pauses your stuff. Sometimes that's useful, but on a desktop that's most often just annoying, particularly if you're just itching or adjusting them.
More mysterious is that tapping them also pauses, but not always, and not reliably enough to actually use to pause and unpause.
Even more mysterious though is the "two finger" tap which changes your headphones mode entirely, so that any background noise stops the noise cancellation. (It calls this "Conversation mode" or something).
But any background noise seems to cancel the noise cancellation, so it's less useful than just turning that off.
But this feature is easy to accidentally turn on, and it took a lot of googling in frustration to work out how to get it back to the normal operation.
God knows what other hidden features these things have, because who bothers to read the manual for a pair of headphones?
