Depends how much you want to spend.
I wouldn’t start the search with Amazon, take a gander at Head-fi.org forums.
Almost all proper headphones should support it, but it’s worth verifying before purchase.
So you’re better off shortlisting headphones you like, then narrowing by multipoint support, rather than only buying based on multipoint.
I use Sennheiser BT-4.50, and they support multipoint. (Frequently available on their outlet store for good prices). I’m almost certain any of the recent Sony XM range will too.
Brains are very good at eventually becoming comfortable with a new normal.
They’re also good at being distracted temporarily.
If you can keep yourself busy with positive things (self improvement, cleaning, exercise, cooking), you give your brain space to become accustomed to the new status quo.
Meeting new people is always a good thing to do too, something to keep the social part of your brain from wallowing. Maybe join a local social activity (walking/hiking groups are great).
Imagine if they introduced a law, that if you had defaulted on your student loans, you were not able to get a passport.
That would reduce the number of highly skilled people leaving the country if it got really shit.
