The VideoMic Me is a high-quality, compact, lightweight directional microphone with a TRRS connector that connects directly to the iPhone's microphone/headphone jack. Its flexible mounting bracket accommodates a wide range of smartphones and allows the microphone to be mounted for use with the primary or front-facing ("selfie") camera. A 3.5mm headphone jack on the back allows for audio playback while recording (app dependent) as well as easy playback of your videos without having to remove the microphone. The VideoMic Me includes a deluxe fur-lined windscreen for outdoor shooting or inclement weather.
