CooMax Mini Spy Earpiece Invisible Earphone Cheat Covert Earpiece for Mobile Phone

I have left my original review below, for the record.HOWEVER3 of the last 4 of these I have ordered, over the last 6 months, have immediately overheated and become unusable. I will, therefore, not be buying from this supplier again.The 4th one never arrived. Not their fault.ORIGINAL REVIEW:This does work if used correctly, but only lasts about 2 months with heavy use I am finding.1) Use rechargeable LITHIUM batteries.2) Anchor the wires from the transmitter using something like a cut down chocbox plate, making sure air can get in the vents.3) Keep your ears clean and use the stick and magnet to get the earpiece in the right position.It is a bit hit and miss, but worthwhile for secret podcast and audiobook listening.

This item came with no instructions wrapped in some old second hand bubble wrap! it failed within 28 seconds of use.I tried Brand new Batteries and different players but Nothing.......! Failed.

Its ok

does not work and it a fire hazard

Cant here at all

As soon as I connected the batteries it began smoking.

It’s a nice science gimmick but in the real world just not loud enough to useable.

Do not buy this, its not what you think it is, i put it in the bin
