Not trying to be mean about it, but I'm struggling to find a reason that will justify this purchase. Maybe if they were like the Peltor headsets that amplify ambient noise and lower loud noises to a comfortable decibel level, I could use that camera to record some footage at the range. However, 720p @ 30fps is honestly below par for action activities, GoPro holds the crown in that area.
seems like an overpriced gimmick. Basically seems like they wanted to take some $30-40 headphones and then jack the price up like crazy by adding a cheap camera unit (similar specs to those $8 1080p video cameras that record to micro SD, and then add a cheap $ 3 bluetooth module and use its GPIO to connect to a dirt cheap accelerometer, and a couple mics likely wired in a way that will provide a differential signal so that some of the noise can be canceled out.
Overall, it seems like a horrible deal. at that price point, you get into the audiophile grade headphones.
When I was a child, daydreaming about James Bond gadgets, I would've probably thought this was a neat idea. As an adult, I can't understand why we would need, desire, or allow network-aware cameras and microphones built into every device we own.
