Mini Bluetooth Earphone, Invisible Wireless Headphone in-Ear Earbud with Microphone, 16 Hours Playing Time Earpiece Car Headset USB Charger for iPhone Samsung Smartphone (Nude)

The fit is good - it doesn't have the rubber thing on the end like the pictures, but it's so small and light that it stays in your ear pretty well as-is.Sound quality is decent. No match for a more expensive set of earbuds - but plenty good enough to enjoy. It can go loud enough to be used in noisy industrial environments.Battery life is pretty good for its size. the charger is very convenient as well.My only complaint is the prompts that happen when the battery begins to run low. The sound cuts completely off, and a voice says "battery low. please charge." ... which would be fine ... except it does this once every ten seconds.This is a problem I've noticed with other cheap bluetooth audio devices as well. They work great until the battery gets low, then you don't get ANY kind of warning - just incessant nag messages that ruin your listening experience completely. I've experienced this with every cheap bluetooth speaker i've tried, and most of the cheap earbuds. essentially, when you get your first prompt you might as well just turn it off until you're near your charger.So if you had TWO of them, you could easily swap them out indefinitely. And that would solve the nag problem.

I had been using another Bluetooth earphone similar to this one for about two months now, but I wanted an alternative with possibly a higher volume level (I listen often while in somewhat high noise environments), the ability to click the earphone button to index to the next track, and a better charging solution.The old earphone is comfortable and works well, but the X12 earphone has all three of those features, and the charging solution is much better than the older one, which uses a proprietary cable that is rather fragile, with the X12 using a sturdy structure with two fixed contacts held onto the earphone with a magnet while charging.The ability to index to the next track is also a small but handy feature that allows the player to stay at the bottom of a pocket if what's being played at the moment is boring.It also turns out that the X12 is capable of playing at a bit higher volume level than the other earphone, another welcome feature.The one knock I have on the X12 is that it has a shorter play time compared to the older earphone, just short of four hours, while the older earphone does between five and six hours.I'm still using the X12 as my main earphone now, but I keep the other earphone in the case with it as a backup for those occasions when I need to listen longer than four hours.

Sound is decent, talk radio is a little muffled, music is not high quality sound but adequate. Battery life is good, 4 hours on one charge. Comfort is good. Overall, a good little earpiece.

The sound quality is good, but the battery life is a joke. This has a very uncomfortable fit in my ear, and keeps falling out. I'd consider it a waste of money.

Keep looking fir something better

The battery life was excellent considering the price. About 5 hours with mid volume. But was uncomfortable for my ear. Felt to hard cause the curves on the earbud are too edgy and not round enough. Might be ok for other ears. I have small hard cartilage ears.

I have purchased and used for extensive periods other mono Bluetooth earpieces, and this one fails on almost every level. Especially battery life, which is horrible. It dies, fast. What I found using this, if you do not power it down while you are not listening, it drains just as fast as if you were using it. The others I have used while on standby barely effected battery life. I do not recommend this. It is very cheap, and it's performance matches the price. If you want a device that will actually work all day, or at least several hours of use, this is not the one.

The battery dies after a few hours of use and doesn’t charge on any connector other than the usb from my car. Other than that good sound quality.
