switch from in-ear to over-ear, want to plug my phone into my stereo.

It's actually hard to buy a single dongle. They're like 4 for $9. So you put one on everything.

For home stereo I bought a Bluetooth dongle and leave that plugged into the stereo.

So it's not perfect, but it's not like you can't plug in your phone.

I was angry about headphone jacks for a long time but it's easier to pick your battles and motion to more important things
