See at Amazon Audio Quality That Separates Amateur From Pro The DJI Mic Mini captures detail-rich audio with noise-canceling technology that removes background hum, wind noise, and the general chaos of recording in real-world environments instead of soundproof studios. You get automatic limiting that prevents distortion when your voice gets loud or excited, saving you from that clipping audio that ruins otherwise perfect takes.
They sound crisp and clear, and do a great job cutting out all of the extra ambient noise that smartphone mics tend to pick up when recording. They're also generally very easy to use, with iPhones automatically preferring the wireless mics, and Android phones just needing them selected in the camera app. They have much better battery life than the slightly older and fancier DJI Mic 2 (9/10, WIRED Review), partially because they don't record locally, but they're a lot cheaper and lighter in return.
