Mic Air New, Unopened Coin-sized and ultra-lightweight - The 7.9g transmitter is discreet and unobtrusive, letting your voice take center stage. High-quality audio - Captures faithful sound with 48kHz sampling. Captures your voice clearly. Advanced noise cancellation and a windscreen capture clear sound without noise, even outdoors. Simple remote control - Video recording, noise cancellation, and mute can be operated from the transmitter. You can focus on the shot, not the setup. Wear it freely - Available with a magnet, clip, or pendant. It flexibly adapts to your style, from interviews to street content. I have opened it in a house where I have a cat, so please refrain from purchasing if you are concerned. There are no smokers in my family.
