Modern smartphones shoot surprisingly high-quality video, with optical zoom, image stabilization, and onboard processing, but even the best out there have generally pretty awful microphones. Thankfully, there are wireless lavalier microphone kits like the DJI Mic Mini you can use to catch crystal clear dialogue, even when you’re on the go. Right now, you can grab the DJI Mic Mini kit with a receiver, two microphones, and a charging case to carry it all on Amazon for just $79, a $20 discount from the usual price.

The most appealing part of this microphone kit is just how easy it is to set up and use. The tiny transmitters don’t drag on clothing, and can be attached with either a clip or via magnets without leaving holes in your shirt. All you have to do is remove them from the case, plug the receiver into your phone’s USB-C port, and start shooting, although Android users will want to double check that the camera app is using the DJI instead of its built-in mic. They even work with digital cameras via the included 3.5-mm TRS cable. You’ll get even more value out of them if you’re already in the DJI ecosystem. Just the other day I wrote about a deal on the DJI Osmo 360, and these actually connect directly to that camera for perfect audio without any extra pieces.

Despite the tiny size and easy setup, the sound that comes through the DJI Mic Mini is pretty impressive, certainly better than any smartphone’s built-in microphones. There are manual gain controls, and you can also use automatic limiting to keep yourself from peaking when a truck drives by. It has two levels of noise canceling, both of which do an impressive job keeping the outside world quiet, so you can sneak in a recording wherever you may end up.

If you’re ready to turn up the volume on your smartphone videos, head over to Amazon to grab the DJI Mic Mini 2 bundle for $79, with various discounts on the individual pieces in case you want to build your own bundle.
