I have a pair of Jabra 65T active earbuds that I bought for $50 and they connect to multiple devices at a time and "just work". If they are connected to my computer and I am watching a video and my phone rings, they switch over without any intervention. At the end of the day when I hop on my Peloton they connect to that without intervention, too.
I am sure the Apple stuff works well too but let's not pretend that they are doing anything unique in this space.
With most BT devices the problem would be if someone else tried to use your Peloton, it'd steal audio from your PC or phone
But Peloton remembers your previously paired audio devices per user; so if someone else uses the bike and has never explicitly paired that set of headphones, they'll show up as an option, but won't automatically pair
