It’s witchcraft, but it works as long as they’re the kind of earbuds that have a volume +/- button on the cord.
1. Aim the camera with the earbuds plugged in to the phone.
2. Press the volume + button.
It’ll minimize selfie-arm (that horrid condition) and make you feel kind of like a middle school photographer, which is always a plus.Turns out anything can become a smartphone stand, like a cassette case.
I had to look up Sugru. Interesting stuff
Anyway - you should use the magnet on the cable, not on the buds. Less likely to damage the buds that way.
