Offered here is 20 PIECES new good quality aftermarket "neck mic" with PTT Switch that works flawlessly with most ALINCO + STANDARD + ICOM + ADI + PRYME + MICROTALK + MAXON series radios. When you hit the PTT button, the supersensitive "mic" picks up vibration around your neck, amplifies and converts it into signals suitable for transmission by your radio. Surrounding noise outside the ear will NOT be transmitted, ensuring that your buddy hears ONLY you.
The "collar mic" will conveniently fits all neck sizes and delivers great sound even in noisy places. A sponge ear cushion is provided to ensure comfortable fit.
