Review on 🎤 Wireless Microphone Headset System with Digital Screen - Dual Function Headset Mic/Handheld Mic for Amplifier, Speaker, PA System - 164ft Range - 1/8'' & 1/4'' Plug - Ideal for Speech, Teaching by Kenkoy Braggs

Super easy to use. Charge, connect to a speaker, any speaker. I use a small UE speaker, it's perfect for indoor practice with the A/C on and the air filter on. I usually speak loudly anyway, but it doesn't require straining my voice at all and the sound is crisp and clear for students. Haven't used it outside but I'm sure it will work great.
