Well, I don’t know if the human ear shape actually helps recording but the Binaural Recording Microphone does look kinda gloomy and cool. At $3,899, we suggest you get this if you have lots of money to burn.
The Binaural Mic from Otokinoko (maker of the Dayon Sound Communicator) is a simple way to record the most realistic sounds possible. Binaural recording allows you to record sounds the same way they are heard in real life by placing the two microphones in the same position as human ears. The resulting playback in omnidirectional 3D sound is more realistic than normal stereo because of the subtle shifts in feeling.
