Review on Walkie Talkie Bluetooth Headset: Noise Cancelling Mic, Hands-Free Earphone Compatible with BaoFeng Kenwood Btech Radios & More by James Richardson

Instructions mean next to nothing to me. There are buttons on the device that I don't understand how to use. Can't find any further instructions online. Bought for use with a security radio but it stops transmitting. I think it's related to accidentally pressing the buttons on the headgear, but can't find any instructions that tell me what I'm doing wrong. I don't like that the device speaks Chinese to me every time I turn it on or off. I would not recommend this product. Will return.
