Review on 🎙️ Professional UHF Wireless Microphone System: 4 Channel with 4 Lavalier Bodypacks, Lapel Mics & Headsets - Ideal for Karaoke, Church, Conference, Wedding Parties by Ryan Person

As the title says, you get what you pay for! It can work as a wireless microphone and it works. If there's an obstacle between the microphone and the receiver, expect things to be less than perfect. Expect the following: Noise - Lots of noise even when the gain is close to 0. There is a lot of crackle with these mics. If you plan on using it for video recording, make sure you give yourself 20 hours of noise reduction and you won't be able to clean it up just because the mic is close to the speaker's mouth . - The LCD is static and cannot be changed. It is for informational purposes only - it is very error prone. Don't bring the phone close - the further away the listener is, the worse the noise. I chose this mainly because I needed 3 mics and it was a setup. Looking back, I should have picked a better product. Lots of people mentioned noise but thought it could be fixed in a post. It's not background noise, so be aware.
