great set of mics that are very easy to set up, clear and have a long range. The little box comes with two microphones, a receiver, a charging cable, a 3.5mm adapter cable, a small mono microphone and instructions. It's easy to charge everything up (they all came with a decent charge) and then plug the receiver into whatever device you're recording with. The receiver connects directly to an iPhone, any USB-C compatible device, or a 3.5mm stereo jack. Two mics mean you can have a backup (if needed) or record two people at once. You could even use one for a music overlay when only one person is speaking. I've used mine for stereo bird shots when filming them with a telephoto lens and it really adds to the atmosphere. Super long battery life (26 hours is probably achievable, the amount of time I've been using it) and the distance is incredible. It would be difficult to need more distance if you need to video what you are recording the sound for. No lag that I can detect, so everything is in sync. Also a good elimination of background noise. You can hear the sound from the microphone. Microphone mute controls are included, and the small microphone easily clips to your clothing. Great price for something that "just works" without fiddling around.
