Review on 🎧 COOMAX Wireless Mini Spy Earphone with Hidden Earpiece Headset and Microphone Detection by Carrie Garling

Conversation speaker - receiver with battery. So far, so good. Now you need a transmitter. The transmitter is a small, brown, candy-shaped triangle that you can see in the photos. You have to hang it around your neck. The problem is that this transmitter has no battery/power. That means it doesn't have the power to transmit the sound signal to the listener. If you don't place the transmitter (the triangular thing) about 1 cm (1/2 inch) close to the earpiece, you won't hear the sound well or you'll hear it very faintly. I did a little research and found that real hidden earbuds come with active transmitters that transmit signals up to 10 meters (30 feet) from the earbud. Has the meaning. And there is a seller on eBay who sells matching transmitters with power for the same price plus an A680 model earphone. So there really is no point in buying earphones without a transmitter. This product is a waste of money and does not give the expected result. And the Q/A section is just ridiculous - the salesperson gives surreal answers like you could even use it in another room. Who are you trying to fool?
