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

These mics sound like a tin can. Don't buy them if you output sound to the system. They may work properly when the audio is being sent for recording and cannot be heard in the room. They are overwhelmingly packed with high frequencies, and no matter how I tweaked the EQ, there was feedback at SOME frequencies. Terrible quality, it's not clear why and how anyone uses it.
