I would love to get this because my volgging skill is improving day by day and its the best time to upgrade my self from an affordable action camera to premium quality action camera

I want to improve my voice quality as well of my video. Earlier I was using mobile camera but there was lots of video stability issues, then I brought an affordable action camera the stability and image quality improved but the oice quality become worst, so now need to improve all of them as my vlog quality has improved drasticly...
