I recently changed they way I do reviews in my videos and needed a lav mic. This Comica CVM-D02 Duel-Head Lavalier Microphone is a great solution for me to film reviews and even interviews with. It will work with iphone and android phones as well as GoPro and DSLR Cameras. I am impressed with this unit. The sound quality of my voice is great especially compared to the on board mic of my camera. The price point is right on and comes with all of the accessories needed. Including pop filters, dead cats, iphone adapter GoPro adapter, and a great little bag. The cable length is very long. I recommend this for anyone needing a duel mic setup.
