The hassle factor is way too high and it doesn't work easily for live streaming from a phone.

I think your fundamental issue might be expecting a phone to be a decent multimedia capture device (phones == content consumption, not content creation). If it's an iPhone and you just care about speech, air pods will be hard to beat.

The Rode product that somebody else mentioned looks like it's worth a try. It's a wireless mic where the receiver plugs into the phone.
