Something funny happened while I was testing the lensgo wireless mic, this was my second "recording a-roll actually because when I was editing the first take I heard all this voice is so great when the preamp on the Sony a7s 3 is turned down completely, When I use other mic I can heard the noise floor should sound like, but this creates something completely different, but oddly enough, When I'm shooting or recording in my makeshift soundproof enclosure, the noise floor isn't there, and the floor there doesn't show anything I hear, so it's a little weird.The second thing that's a little weird is that depending on what environment you're in, the lavalier mic itself sound great in this room, but it sounds great in a soundproof enclosure if I'm not. Using a lavalier mic and using the built-in mic. The built-in mic sounds great in this unsound room, not so good in a soundproof enclosure. So I'm not sure what's going on here maybe there's actually more postprocessing going on in the receiver than I know it's actually listening because I don't know how often it goes in and out and then it tries to make its own little tweaks , this is good, it can make your voice sound better, and it is also easier to adjust and edit later. You should try it out for yourself to know the advantages. At the same time, this lavalier microphone can be used for mobile phones, which is really convenient for current photographers to work.
