Works better than I expected. The cable is long enough to fit under clothing, clip to the lapel of a person speaking into a microphone, and remain outside the frame of an iPhone video. I was looking for a convenient, quick solution for spontaneous patient feedback in our clinic and it's VERY easy to set up (within 1 minute). A dual microphone is crucial when you are recording an interview in a public place and need to filter out background noise to hear the recorded dialogue clearly. It also allows the interviewee to speak in their normal natural tone without worrying about their own audio being picked up by the recording device (smartphone/DSLR camera). They wrap the cord for storage. It fits better in a small cloth bag and is easier to pull apart when you're ready to use it.
