Review on 🎧 MaximalPower RHF 617-1N X3 3.5mm Receiver/Listen Only Surveillance Headset Earpiece, 3 Pack: High-quality Audio Solution for Enhanced Monitoring and Covert Operations by Richard Koh

I wish they had a little better connection system. I wear them with a safety vest and the clips get a bit uncomfortable (at times). The headphone side is a metal alligator clip which is very secure but a little larger than necessary, the plug side is a small plastic clip which could be a bit stronger. Don't get me wrong, I've bought a lot of these - for myself and others. This is a great tool for people who have to carry two-way radios at work all day.
