Bluetooth is a bigger hastle than just plugging in a wire.
What? Literally every single pair of Bluetooth headphones I own auto connect to my phone by the time I have both buds in my ears.
And all the cheap ones use Micro-B instead of C for charging
I bought a cheap pair of $20 anker ones a couple years ago for gardening and they’re USB c. Even the cheapo taotronics I got from AliExpress were USB c. I don’t think micro has been in use for a while now.
Buy a third set and then pick two devices for each pair.
