does this have a mic built into it?

No, it uses the built in mic on your headphones - it includes a PTT button

Which trrs headset standard is this wired for, omtp or ctia?

Apple, mic on shield. It comes with a reversing cable for ground on shield

Will this work with a TYT md380u dogital radio?

No will not work with any radio because PTT button does not work

Can't get it to work with Apple Earbuds with 3.5 mm jack? Is there a specific earbud that works with these? Thanks

Mine works with a Sony headphone and a Sony earbud. If you have a headphone with a 3.5 MM Jack I would try that and if it doesn’t work I would think that you’re adapter is defective.
