The biggest problem with action cameras, pretty much any action camera, is the microphone. Whether it’s the original YI HD, the YI4K or even a GoPro, their sound just tends to suck pretty badly. But, it’s not really a surprise. The main intent of action cameras is for recording fast sports action with a wide field of view. There’s all kinds of noise going on that makes it virtually impossible to distinguish a voice easily anyway.
But, a lot have started using them for things like vlogging and family trips, because they’re small and lightweight. For these people, sound is important. Here are two videos which show a couple of different hacks to help you get a bit better sound out of your YI Action Camera. The first, by MrCsami swaps out the built in microphone for one with a built in wind guard. The second from shinyside removes the microphone completely, replacing it with a 3.5mm jack to use whatever microphone you wish.
