My earphones are two years old and can be paired to dozens (I’ve not yet hit a hard limit) of devices and can be connected to two sources concurrently with the ability to swap connections between any of the other active devices on the fly using the earphones iPhone app (so you’re not manually disconnecting devices).
As an audiophile I also don’t think Sony are the greatest example because in my experience Sony haven’t been making the best audio equipment for several decades (despite their price point and cult following).
unfortunately they (airpods pro) seem
to stay connected to only a single device, which is a shame. my other daily use headphones (qc35) can be connected to 2 devices in the same time and it helps as when someone calls me
on the phone it pauses the laptop music and switches to the call.
Even the top of the line and extremely well rated Sony WH-1000XM3 headphones will only connect (not pair) to a single bluetooth device at a time. If you want to switch audio from your laptop to your phone you got to manually disable the connection on one device, and connect again on the other. That is quite clunky if you have like 3 PCs (work/home) and a phone and would love to use your headphones with any of them.
As far as I understand the Airpods might at least not require to manually disable the connection when switching to a different device. But I can't say for sure, since I don't own a set.
