UPDATE: Akaso made this right!On 03/16/2021 I was contacted by Akaso support. In short, they were very disappointed my previous experience wasn't satisfactory, and in order to make things right, offered a replacement camera free of charge. The replacement camera was a V50 Pro, which I feel is comparable to the V50X for my needs, and it is working well. Obviously whatever support issues they may have had are being addressed, and customer satisfaction is their goal. Our communications were clear, professional, and amicable. Their currently demonstrated dedication to customer satisfaction is what I look for in a company, and I would buy from them again. As for the V50X I originally bought, it appears they had identified the problem and made corrections to production of new units. They have told me they are NOT having the audio issues in the newer V50X cameras. I just happened to receive an older one that had the issue.In summary, you should be able to buy a new Akaso V50X with confidence in the camera, as well as Akaso .----------------------------------------------------------------------------------------------------------------------------------01/04/2021 Original reviewSummary: Audio unusable via Akaso V50X internal mic, or the external mic Akaso specifically makes for the V50X. Neither Akaso or Amazon support were able to correct the issue.Details: Recorded audio level was so low with either internal or external mic that it almost could not be heard at all at full volume playback on either the camera itself, or when the file was transferred to a PC. All camera settings were checked and found to be correct, and most recent firmware was on the camera. Neither Akaso or Amazon support were able to correct the issue.Takeaway: Now seeing many non-Amazon reviews indicating this issue is more common than not. Do a LOT of research before you buy this camera or its external microphone.
