I would suggest looking at some IEMs if you want to stick with a wire. For phones that don't have a headphone jack, a USB C to TRS jack (tip ring sleeve / headphone jack) will suffice.
Personally I prefer a good quality BT/USB Dac amp to drive my IEMs as the quality is far superior to any phone headphone jack that isn't a LG V20 thru V60, or the Moondrop MIAD01 DAC phone. Few manufacturers provide good onboard sound. BT buds improve upon this a lot, but a real dac amp and set of IEMs or cans will show you so, so much more.
You can sorta cheat at this with a USBC DAC/dongle (converts USB C to a headphone jack) and just pass the dongled cord around.
Have you seen Return to Oz? It's a hell of a ride. Disney wants everyone to forget this exists.
I have had not one, but two power outages during haircuts. My wife usually does them at home, and on two occasions now, I've had to have half a haircut for a bit. We all had a good laugh.
Once was weather related. The other was a car which took out an upstream power pole.
