bluetooth audio is great because instead of the horrible inconvenience of plugging in an audio cable into the audio hole, I get to just put the earbuds into my ears, open the bluetooth device list on my desktop, not see them there, pull out my phone, check if it's connected, find out that it's not, realize that it probably automatically paired to my laptop that's laying in the other corner of the room, then google "WF-1000XM4 pairing mode", find a page that tells me what I need to press for how long to switch it into pairing mode, and only then I can start using them
