I’m pretty happy with Pixels for the moment, so it’s a $5 USB-C to 1/8" dongle for me. That or the Pixel Buds I got for free as as promo with the phone. I’ve never had to charge and use the converter at the same time, but I believe there are cheap dongles that can do that too.
Looks cool. My RPi 1 is still rolling along running Pi Hole, but if I need to replace it, something like this running off PoE would be very tidy.
