I was looking for an "action camera" to video backpacking and vacation adventures, but didn't want to spend GoPro money. After reading and watching a lot of reviews, I decided on the V50X especially since they had just supposedly "fixed the audio" in June. I assumed this meant the low audio volume many reviewers had complained about, but that wasn't fixed so I'm not sure what actually was. The latest firmware was still from Nov 2019. I did contact Akaso support about this, and they did reply most times within a day or two (they are in China) but considered my test videos showing the audio level issue "normal" and offered a full refund.To summarize, if you have either the internal or the special external mic within about 6" of your mouth there is no real problem with volume level. However the gain drops off very quickly after that and is at least 12 dB below "normal" if you have either mic at 18", which is typical distance for selfie videos. The V50X video volume was much lower than videos taken at 18" with either my Canon Powershot S120 camera or Moto G5 Plus smartphone.So far I've only gotten to use it for my big backpacking trip (European trip was canceled) and it did very well. My audio solution was to use the external mic clipped to my shoulder strap and talk louder or I held it near my mouth if I didn't have my backpack on. The provided windscreen is OK for light breezes, but I knew it wouldn't work for the windy conditions I would face so I made a much thicker one from an old sponge, which worked great even in 40+ MPH winds.The only other complaint I have is it wasn't clear that Distortion Calibration and Image Stabilization are mutually exclusive so turning one on turns the other off so I didn't notice IS was off for a little bit. The IS does work pretty well though not quite as good as my old Canon S120 camera. It sort of "jumps" slightly as the scene is moving. One other annoyance is it is easy to get smudges or prints on the unprotected lens, but I assume all action cameras are the same in that regard.1080 video looks good. I only did one slow motion clip but used the video time lapse several times. Battery life was as advertised. I didn't use the V50X for pictures since I used my Canon S120 for that so I can't comment on that aspect. I also didn't use it in the underwater housing yet. That will occur while snorkeling this coming summer (hopefully). The touchscreen and settings were easy to use.Overall, the V50X is a very capable and feature-packed camera for the price. I'm impressed with what I got for the money. I just wish the audio gain was better though one benefit of this issue is there is less background noise.
