Review on 🔊 Retevis EAK004 Hands-Free Walkie Talkie Earpiece with Mic 2 Pin, Compatible with RT22 RT21 H-777 RT68 RT19 Baofeng UV-5R pxton Walkie Talkies, Acoustic Tube Two-Way Radio Headset (1 Pack) by Jessie Ritchie

I bought these headphones to use in a theatrical performance to carry signals between the director, the director and the sound/light booth. The play was a musical. The headphones picked up so much background noise that we had to wait until the end of the musical number to call out a clue. The rest of the lines had to be taken with the script without asking the director. It was also difficult to adjust the microphone to the ideal distance from the headset so that speech is not distorted. It was helpful, but not what I was hoping for.
