Great battery life, very good sound quality for calls. Overall, it's worth its money.
On 16/3/23, the cable got cut.

Perfect little gadget, it's worth it!!!!
03/03/2022 I have to mention that it fell into the bucket of the mop, full of water, detergent, and chlorine.
I rinsed it with plenty of water, used a hairdryer with cold air, and left it in a container filled with rice for four days. I took it out and left it in the house environment for two weeks. Today I turned it on and it worked perfectly, crystal clear sound, and it's also time to charge it.
It charged normally and I'm amazed!!!!
It's like nothing new happened again!!!!

It is very good for its price, the most durable of what I have bought.... If you take care of it a little in the pulling of the headphones, it has no problem. The vibration is very helpful!

Unacceptable after 2 months and not full functionality as a second one stopped working, you can't hear the speaker and you can't hear anything.

It should grip tighter on the ear so that it doesn't easily come off with a sudden movement, or maybe it could have a slightly longer headphone cable

I have bought 5. I distributed them to my colleagues and they are all satisfied with heavy use.
I don't believe the comments I read.

Well, after a year, 2 out of the 5 broke but they easily replaced them with new ones. The rest are perfect. In other words, it should be a good piece for you, but they will replace it if you have a problem.

It broke very easily. It's not worth the 13 euros I paid. I actually paid 26 because I bought two. Both of them broke in 3 weeks. I do not recommend it. Get something else.

After 2 months of regular use, the cable "opened" in the connection area with the headset. Another problem it had was that when you were already on a call and someone else called you at the same time, it would automatically disconnect. When you move away from the range of your mobile, it starts vibrating annoyingly... I will prefer something else...

Positives:
As an idea, it is very practical... you can attach it to your clothes and you don't need to wear it constantly on your ear, but only when you have a call.

Negatives:
1. The connection cable with the headset is fragile, as it broke after two months and even though it was connected to my device, when I answered or made calls, I couldn't hear anything while others could hear me!
2. It has vibration, and when I moved 5-10 meters away, it would give a signal every few seconds, indicating that I was moving away from the device with a strong vibration, which was very annoying because people around me noticed it... For example, my boss in the office... I had to take it off to prevent this from happening.
3. The connection speed with my mobile was much slower than other Bluetooth devices I had in the past.

I would not buy it again!
