hungryeye. Thanks for the tips but not where I want the camera. I do agree with the foam idea (I also have senas), just can't be implemented in my case even tho I have tried. The Sony HDR AS100's have a stereo mic just below the lens so literally trying anything there gets it into the shot.
External mics for them would work but they are a bit of a crap design for that. In their protective case the mic' port cannot be reached, outside of their case with a mount attached the mic' port can't be accessed either even tho it is still weather proof because the camera mount goes over the port.
Using a skeleton case you can reach the port but it is no longer weather proof with the door open (I thought about about a sealant here) and you can't use the lens protector (Thought about a dremil here to make it fit). Even if I did all that I would lose the bottom mount and not be able to rotate it while I was riding and this I have discovered is something I don't want to do.
I have also tried a cheap voice recorder with a plan to sinc' the sound later however the external mic' was overpowered even at idle. I tried with no external mic' in the back pocket but that didn't work either.
All in all a very bad design if a external mic' is a priority tho sooner or later I will work something out. Apart from that I have found them to be very good cameras for what I want. I didn't think any of the bike mounted cam' footage would have been usable because of all the flopping around it was doing but the stabilization did an amazing job.
