Sound Quality Comparison-- Iphone 4 vs GoPro HD Hero2

My Channel: http://www.youtube.com/user/BuffmanLT1

I got a HD Hero2 for my birthday, and I wanted to compare sound quality between what I currently use for my videos (Iphone 4) to the new Hero2. All three videos use the same 40gr Winchester HP .22WMR. We shot with the Hero2 with the case and skeleton back, and without any case at all.

My Observations:

The Iphone 4 had the best quality, but is on the quieter side, and doesn't pick up the bass as well. The Hero2 in the case with skeleton back had the most muffled and distorted sounding, while without the case was close to the Iphone 4 clarity, but picked up more reverb from the gunshot. All in all, very happy with the Hero2, as it will prove a lot more versatile then relying on my phone to shoot videos
