External wireless mic for lg g4

I want to make my videos better and i want to know if this can be done

I have a lg g4 and lg g3. Is it possible i can turn my lg g3 into a bluetooth mic for my lg g4

I want my voice heard clear even if my g4 is far away from me. Hope it can be done or please recommend me some compatible mics that will work with this phone. Thanks
