I’m always surprised at how people seem to assign zero value to seamless switching of headphones between iPhones, MacBooks, Vision Pros etc. Only those who haven’t been spoiled by the luxury of not having to even think before just starting to play music from a laptop when music on your phone was already playing into your headphones could think this way…
My ~6 year old Jabra headphones connect to two devices simultaneously, and can easily switch between a total of five at the touch of a button. My Pixel Buds do the same (called 'multipoint' and 'audio switch').
Yeah, things were more awkward in the mid 2010s, but I'd expect everything from the current decade to be able to do it without issue.
