Simply a ridiculous product. Not even close to the waiting times it claims. On the first charge, I left it plugged in for several hours. I made the pairing for the first time and it showed a battery available at 80%. I didn't pay attention and had it connected to my phone for about three hours without using it for any calls. When I checked after 3 hours, it was disconnected, I reconnected it and checked that the battery level had dropped to 30%. I talked for 2 minutes and it dropped to 20%, and from then on, a Chinese voice was heard saying something but I couldn't... probably warning that the battery was running out. Well, that's when it got kicked and probably still flies... Good luck to whoever got stuck with it and the rest STAY AWAY!!!

Everything is fine with one significant problem!!!! If you hold down the button, it redials the last number!!! However, the button protrudes, so it is easily pressed, resulting in me having my phone in my bag along with the Bluetooth and calling the last number - from a few to maaaaany times - without even realizing it!!!!!!! They call me or send me anxious messages to find out what's happening!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! So, I have to turn off the Bluetooth to stop calling them!!!!!!

Extremely durable. We use them daily. My wife's (6 months of use) fell into a glass of water and mine (3 months of use) was washed in the washing machine along with my jacket. After drying them - during warm days - in the car, they function normally!

Note: They got wet at different times...
...and it only speaks Chinese but I don't care (kilien-kie = connected)

First of all, its language is only in Chinese. I couldn't connect it to my phone. I immediately threw it away. Hello, 15.00 Euros.

It is quite affordable compared to the others, but the quality of the conversation is not good enough. Sometimes I could only hear the interlocutor approximately. It's like there are constantly parasites in the connection.

I have it for over a year.
It has very poor sound, I can't hear my interlocutor clearly, so I end up taking it out and speaking directly from the phone. This alone is enough reason for me to replace it.
(It has been extended because I use the car's hands-free feature.
It disconnects all the time without moving it away from the phone.

The fit in the ear and battery life are OK.

Incredible number of reviews! That's how I fell for it and bought it.
Personally, I consider it a mediocre to bad Bluetooth. Let's say it sits comfortably in the ear without causing much fatigue. The call quality is satisfactory for now. The biggest drawbacks for me are the sound, which is loud but mediocre to bad when it comes to music. Also, the battery life is poor. About 5 hours with music usage! Although it's cheap, I believe you can find something better for the money with a little luck and searching.
P.S. Is it possible for you to have the main button up there? It's the only one that's easy to press.

It does not have good sound. I used to have electronics, but unfortunately I can no longer find them, production has stopped. So I went for this one. The sound is not good. It disconnects easily, even though it shows that it is connected. In the end, I end up talking on the phone. And if by chance you close it while talking on the phone, the conversation stops and you end up cursing Mao Zedong afterwards... wasted money

Frequently disconnects. The sound quality is terrible... while the music playback is good. The battery life is satisfactory, lasts the whole day.

I pay the price difference because I want the product in pink version and they send it to me in white. The basics, gentlemen...

It doesn't fit well in my ear. But my friend likes it because she got the same one.
The sound is good. It connects easily.
They can hear me without noise.
It needs to be charged every day.

Great attention, there are imitations circulating, if you get the genuine one, it delivers even more than what it promises! I have tried both Plantronics and Samsung, and of course, it can compare and surpass them even though it is only 1/3 of the price of the others!!!
The language changes easily, just press volume+ and volume- at the same time!!! And my first impression when I held it in my hands was that it would be a typical Chinese one, I was afraid of the plastic casing, but it has withstood falls and everyday use! Also, the packaging includes a second rubber case in case it breaks or gets lost, something that Samsung does not do!

I have connected it to two Huawei P20 devices, but after a while, it disconnects from one of them (not always the same one) for no reason at all.... During calls, there is a annoying sound at regular intervals... Not convenient at all for someone who is driving!!!

Third time I buy it, lost one, the other one was destroyed by my little one. Very good tool, worth much more than its cost, I wonder about the negative reviews

It is excellent, I have connected simultaneously an Android and an old Nokia C2-5. I drive and have hands-free in both phones. Also, if you search on YouTube, there is a way to change the language to English by pressing a combination of buttons. Excellent sound and almost free, only 10 euros.

First of all, not all the information that is heard from the device is like having Jackie Chan with you. EVERYTHING is in Chinese. When asked at the store where it was purchased, the answer was that the manufacturer is Chinese, the importer is Chinese, so everything is Chinese. Sorry, but no. Other than that, it is not for many hours in the ear. The sound is decent. The battery life is expected.

Tragic! The sound is very bad, compressed/distorted and very bass-heavy (I tested it on 3 different smartphones). Very uncomfortable in the ear, unbearable, you take it off within a few minutes. Also, the buttons are very hard and it hurts the ear when you press them.
I threw it away in 2 days. Money wasted.

For the money, it is very good, without interruptions and relatively comfortable, as long as you don't wear it for a long time. It doesn't fit well with a helmet because the answer button touches the helmet and opens and closes on its own

It is what we call value for money... it does its job perfectly and for this price of €10.79, it is great... not to mention that it is the best for this price!

Very good product with perfect sound. Beware of imitations (see https://youtu.be/7Ud7QFS8Jw8). The fake one has no quality relation to the genuine one.

I got it yesterday. I really didn't expect it to be better than a Samsung that I had bought for 20€. Also, you can hear others clearly and they can hear you clearly. It has good bass with certain songs, but there's no problem.
