Review on 🎧 Enhance Radio Communication with Maximal Power RHF 617-1N 3.5mm Surveillance Plug Receiver/Listen Only Audio Earpiece - Pack of 2 by Jack Ford

This is a great product for many reasons. I work in law enforcement and that works well for this app. However, they don't last very long. That's why I buy several at once. They fail anywhere from a few months to six months. The sound starts to come out of the small connection node to which everything goes, and not out of the speaker. So you need to change them regularly. That's why I gave a few stars less. I buy them and they work well for the limited time they work and for the money it's good. I don't think that more expensive devices will perform differently either. I'd recommend buying them, but I'd say you're better off buying a few to keep on hand.
