In my test of the Rode VideoMicro, I concluded that the cheaper, smaller microphone provided a richer sound than what you would get with the Rode VideoMic Pro for more than 4 times less money. The VideoMic Pro retails for $229 while the VideoMicro is available for $59. The VideoMicro offers excellent bang for your buck. Check out my unboxing and audio test.
