Sometimes the microphone doesn't sound and you have to unplug and plug in the plug again to make good contact. Otherwise, no problem and they have very good sound isolation from the environment.

For their price, the headphones are satisfactory. The sound is quite good, but the microphone needs to be held close to your mouth to be heard. It isolates the sound quite well, but the ear cushions become uncomfortable after some time (about an hour). For the money I paid, it's okay.

The headphones are simply awful. First of all, you can only hear from one earphone and the sound quality is very poor. What can I say, they are just terrible. Do not buy them

I came from the beginning with one earphone only working... Low build quality. I wouldn't buy them again. Better to spend 5-10€ more for something much better.

Stay away!
I bought them in May (2020) and they didn't last even a month with simple and careful use. The problem occurred with the cable that had to be in a specific position for both to work. The price may seem attractive, but stay away from Rebeltec headphones, go for JBL or Sony a thousand times. Also, I forgot to mention that their ear cushions are very hard, resulting in ear pain after 10-15 minutes of use

From the 1st day of use, the volume is very low and there is no adjustment, the computer does not recognize the microphone, the 1 headphone does not work, almost 11€ wasted with shipping.

A decent quality and they serve their purpose (for their price). But I have only tried them for one day. I received them yesterday. So far, they are fine.

I bought 2 pairs. One of them broke easily after a fall. The other one, after a few months, only one earphone works. Overall, they are very mediocre even though they look nice. I wouldn't buy them again. The quality is from bad to mediocre.

I bought two pairs for the kids. The first pair, on the second week, fell off the ears, resulting in one speaker not working. The second pair, with careful use, after two months, one speaker sometimes plays and sometimes doesn't, and in some songs, you can only hear the music and not the lyrics. If the damage in the first pair was due to misuse, the malfunction in the second pair cannot be justified with careful (almost meticulous) use. They look nice, they are convenient, and they have good sound as long as they work, but in terms of durability, they are below average to poor (compared to a pair I bought later, to replace the first one, from a supermarket chain expert with a similar price much lower).

Just by isolating the penetrating sound produced by the vocal cords of your spouse, so that you can indulge undisturbed in your favorite habit, such as watching all kinds of comedic situations on the internet, they have already achieved their purpose.

I don't know if I'm the only one with this problem, but from the left side, the sound is louder and I had to adjust it from the computer's sound settings.

I wanted to buy headphones but I didn't want to spend a lot of money because I break them easily.
For the price, they are great and of course, you can also make calls because they have a microphone.
Very satisfied.
