Ive seen these, I like the feature to allow everyone in the group your riding with to have their voice audio recorded as well. Cool idea, but I still can't help but think another thing to drain the already short GoPro battery life. and I think a waterproof case would be awesome rather than the frame style.
i believe the gp10 has its own battery and it just clips to the back of the go pro. and they have a waterproof case http://www.buysenabluetooth.com/camera-audio-pack/gp10-a0202.html
Here is my main question...would viewers find the inane chatter between myself and my riding buddies to be annoying?
Most of my videos have limited commentary. I just got a better mic setup so I could try doing a little more. Most of my riding buddies just got Sena BT comm setups and I was thinking of also trying the Sena backpack for some upcoming rides, but I fear that I may just end up recording hours of middle aged men calling each other fat and stupid.
