Review on Yolipar Single-Wire Earpiece Surveillance Kit - Compatible with BaoFeng, BTECH, Kenwood, Arcshell AR-5 Walkie Talkie - PTT Mic D-Shaped Clip-Ear Headset by Sammie Rodriguez

When connected to Baofeng UV-5R, this earphone will automatically transmit the signal. When I press the transmit button on the earbud it stops transmitting, but when I press the transmit button again it doesn't transmit. I have tried starting with the radio on and again with the radio off, the behavior is the same. It seems my returns window has closed so I can't return or exchange it.
