These worked very well for a video project I was doing

For my purposes (making simple videos for use to promotoe a non-profit organzation at minimum cost), it is working fine so far.

I also use the iPhone app Kinomatic for more manual video controls and these mics work great with it.

Everything was working great then all of a sudden after about 2 months it almost completely stopped working

One worked really good, but the other two were very quite and one simply did not work.

The mic works fine

Anyway, this new mic works great

This worked and the new clip didn't break

There is a miniRCA to dual female RCA adaptor but that's absolutley useless for using w a smartphone
