Mini Hidden Spy Earphone Wireless Earpiece Headset Microphone Detection

Lovely - One of the MOST successful hidden ear pieces ever!USE: It goes all the near the ear drum, yet easy to remove holding it's tailVISIBILITY: it is completely hiddenMUSIC: the sound quality is NOT meant for playing Music but for human voice which is clear enoughCONTROL: the volume is controlled by phone volume controlsEASY OF USE: easily plugs in the headphone jack just like a regular headphoneBLUETOOTH: Are you kidding me? This is a typical phone headphone jack compatible, not a BluetoothCONCEAL CABLE: the thick cream color cable is to be worn around the neck UNDER THE SHIRT and the ear phone ONLY works when it is in the middle of the think cream cable, it has to be in the frequency to workEAR BURSTING VOLUME?: the volume is relatively mild to high if you place it correctly & deep enough with it's tiny speaker opening towards the ear drumDOES IT GET TOO HOT: Again, are you kidding me? It's a 1.5 DC Volt, can NOT be more harmless, yes it does get slightly warm but you will NOT even feel it, I never did feel it, may be if you were to take a infrared heater lolENVIRONMENT: clear enough to be used in slightly noisy environments like debates, classrooms etc, but, the more silent the betterMICROPHONE SENSITIVITY: the mic is sensitive enough, just make sure to NOT rub it under your shirt - sit down, don't move too much, the fabric can rub over the mic via movements and the other person on the phone may not hear you well, so I keep the mic exposed but remainder cable in - works great for me... It also worked great when it was under the shirt, I wore a black shirt. Even if you keep the pic exposed there is NO physical connection like a wire between your ear and the mic - this is a HUGE advantage. Try wearing a thin shirt and dark color shirt out of common sense, do NOT hear jacket or heavy cotton shirt and expect the sound to pass thru heavy blankets.BUT THE BAD REIVEWS: Well, it is a delicate device, if you insert the battery the wrong way and press it, it WILL break buddy, if you pull the battery door tooo hard it will break, it is made of plastic and elastic!! If you are going to handle it appropriately it will NOT breakHOW LONG HAVE I HAD IT?: At least 4 to 6 months I guess, I have even bought extra batteries for it, already drained one battery and the volume had gotten very low, I use it for 15 mintues to 1 hour at a time, sometimes just for about 5 minutes depending on that "Video" conference and I need help delivering presentations or when I need to go to a client meeting with my manager delivering current market statics in my head literally! It fits in your ear canal.BUT, THE SO MANY BAD REIVEWS: That is the exact reason I am writing this detailed review, just think how delicate you have to handle small components like delicately handling quarts watch minute hand, hour hand, seconds hand then you will be able to understand the plastic built is pretty strong considering it's size and yes there are small components inside so just be careful while inserting and removing battery, take care of the positive side and the negative side of the battery..I will buy this again!! It lasted me so many months!

I really wanted this to work out. This is something I've been looking for and it seemed perfect. After reading the reviews, I felt I had a 50-50 chance. Most people either loved it or had absolutely no success with this item. I fall into the ladder group. First time I tried it, and inserted the battery correctly, there was a hum in my ear, but I could never get any audio. No music, no phone calls nothing. I did everything I was supposed to do and wore the wire against my skin. I performed my due diligence by opening the other battery, because two batteries come with this unit, and inserted it into the earpiece the correct way, and I didn't even hear a hum. It was completely silent. Perhaps I received a faulty unit. Either way, it didn't work for me and I now have to find an alternative so if there are any suggestions out there, please let me know. Again I really wanted this to work, but I had zero success with it.

So I thought mine was broken as it either made a weird scratchy sound or no sound at all when I screwed on the cap that holds the battery in, but I think the issue was my phone wasn't pushing enough volume so on a whim I downloaded the volume GOODEV booster app. Keep in mind the audio quality isn't great but it was absolutely perfect for my talk that I gave I was able to maintain perfect eye contact and this is exactly what I needed so I give it five stars because it did exactly what I needed to do. I wouldn't recommend listening to music on it or something like that but if you need to hear something discreetly get a volume booster app for your phone and it'll work great

The earpiece is a receiver with a battery. So far so good. What you now need is a transmitter. The transmitter is this tan-colored little candy-shaped triangle you can see on the pictures. You are supposed to hang that one around your neck.The problem is, this transmitter has no battery/no power. So, it has no power to transmit the signal the sound to the earpiece. Unless you place the transmitter (triangle thing) close to about 1 cm (1/2 inch) to the earpiece, you won't hear the sound well, or just very faint.I did some research and found out that the real hidden earpieces come with powered transmitters that transmit signals up to 10 meters (30 feet) to the earpiece. Makes sense. And on eBay there are seller that sells the suitable transmitters with power for the same price plus the earbud model A680.So, there is no reason to buy an earpiece without the transmitter, actually. This product is a waste of money and provides not the intended result. And the Q/A section is just ridiculous — the seller provides some surreal responses, like you could even use this being in another room. Who are you trying to fool?

Buen producto

The COOMAX Mini Spy Earphone is impressively small and quite discreet. However, setting it up was more complicated than I expected, and the instructions weren't very clear. The sound quality is just okay – good enough for casual use but not for anything too critical. It's a neat gadget, but it could definitely use some improvements in user-friendliness and sound clarity.

Why did you pick this product vs others?:No good quality

Not one to write many reviews but I am happy with my purchase.Considering the size of the super discrete earpiece it will of course limitations but it works!!Battery last about 5-6 hours, so I simply pack a few spares to get me through my 10 hour work day!Also, not meant for music but works perfectly for podcast, youtube audio and auido books. It also suffers with inteferance on electrical devices, so consider your surroundings before making the purchase.Overall very happy!! Thanks!
