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

I was really worried about how well this device would work but it is absolutely amazing. However it took almost an hour for me to figure out how to get the earpieces placed correctly. It reminded me of learning to use contacts, it took a while to get it right but once I knew how it went quicker and after I practiced a few times I had it down. It is necessary to allow the earpiece to go all the way into the ear, if you don't hear it drop in your ear you have done it wrong. I found it was best to lay my head on a table and drop the earpiece into my ear. Then I held the ear canal closed on the side with the earpiece already in it to put the earpiece in the other side. Once both were in place, I shook my head a couple times to fine tune the sound and I was good to go. Though the sound was clear with only one earpiece in I wanted to know if I could get both earpieces at once. I've been wearing them around the house and so far the system has stood up to housework without any issues, it's still hidden and playing perfectly. I can hear the audio while standing close to the tv at normal to loud volume, but the vacuum was way too loud, I couldn't hear anything. (I have just had my hearing tested and I have average hearing.) Further experimenting proved that if I turn my head sideways and shake my head the earpieces will fall out or at least fall away from the ear drum so I can't hear it. Also if I jerk my head at whiplash like speeds I can dislodge the earpieces. The neck ring/wire is visible if you wear really tight clothing but is hidden under a normal form fitting T-Shirt. I'm busty so the batteries can fit nicely in a sports bra, I would recommend a money belt or something worn around the waist for greater stealth if you don't wear a bra like mine. It also comes with a handy on off button that turns the audio off on my phone. (I'm currently using my phones music playlist for testing.) I am not sure that this device is meant for hard use and I wouldn't want to get it wet but for the price it's a pretty handy device.

1) Doesnt work unless you put the neck cable literaly over your ears and even then the sound was soo poor and low that I could only understand 1 out of 4 every words my gf was saying. Music is not an option cus you will hear echos from an alien space ship. 2) POOR DESIGN / CHEAP MATERIALS: The box wont fully seal, the battery terminals that clips on the 9V battery almost broke when I was trying to get them off the first and only time I used it. 3) It overheated 1 mins after use, then 3 mins later it was soo hot to the point the whole living roomstarted to smell like burnt plastic. No fumes obsereved or melting but the heat and smell was enough indicative that fire is immenent if I continue to use it for another 5 mins. DO NOT BUY, THIS IS A SCAM. I returned mine the very next day, dont waste your time because you will end up doing the same thing unless I got a really bad package, but even if thats the case, I would buy this product just because of the poor design and cheap workmanship. Good luck.

Very small and fits in the ear very easily. I used it to listed to music while doing work inside and outside, and it while very low quality it was good enough to make out most of the lyrics and tunes. I purchased some rechargeable 9v batteries for about $15 and they lasted about 10 hours per charge. I absolutely loved it until just the other day when it stopped working - I don't know why, perhaps because some sweat got into it, perhaps because it overheated, I don't know. But I may order one again, and would certainly recommend.

Super small and would be very easy to hide. Haven’t actually used it yet but I can’t wait to see how good the sound quality is.

La realidad es que si funcionan muy bien pero al mismo tiempo tienen muchos cables y tantas conexiones que hacen muy difícil llevarlos puestos. Mejorando eso el producto quedaría 100 de 100

Terrible product don’t buy doesn’t work as advertised. You can barely hear anything that’s even when you’re in a room with nothing on it’s very hard to hear through this thing.

Use them I listen to stuff at work. Fine for 2 days then fell apart. Batteries heated up. Magnet positioning is finnicky and took a couple tries.

Didn’t think they would work , ten years ago I would never believe it , but they work great, came with 2 ear pieces though I was only getting one

I put my money into garbage i swear not working at all

Havent tested as just revived and there are no earpieces included

No me gustó porque no se oye nada.

Je l’ai reçu rapidement et tout est comme decrit

Absolute garbage product designed to scam buyers. can barely make out any sound even if you hold the loop right to your ear. flimsy. AND ONLY GOT 1 EAR PIECE.
