On the plus side:
1) They hear me clearly, and I can hear them well too.
2) The battery lasts as long as the manufacturer claims.

On the negative side:
1) They don't have much bass at all.
2) They don't fit well in the ears at all. You might say that they don't fit well in my ears, but I will respond that I never had this issue with other headphones. Even though I bought 4 different types of ear tips and tried them all, they didn't fit me well. And of course, if you dare to use different ear tips, they may not make contact with the charging contacts on the case, so they won't charge.
3) Due to Bluetooth 5.0, they have a short range.

I have had these headphones for about 2 years now, their sound is pretty good but not perfect. I bought them for around €15, so I believe they are a great value for money. The case scratches easily, I put them in my pocket with my keys and it got filled with scratches. Overall, they are a mediocre pair of headphones, I would rather get the QCY T13 ANC for the price. Lastly, the microphone is pretty good for calls.

In terms of sound quality and application, it's great. The aptx makes a difference overall and the touch controls were also great. However, in just one month of minimal use, the right one broke, resulting in very low sound and rendering them useless. Nevertheless, considering the price they are definitely worth it

Many times the right earphone takes a long time to connect. The sound is very basic. I wouldn't consider them value for money.

Very good headphones for their price. Clear sound with the bass where it should be, they seem sturdy with good build quality, battery life is okay but you can charge them several times in the case they have and overall I didn't have any issues. Only at the beginning when I was listening to music, one of the two would lose connection for a bit but now they work perfectly. I recommend them!

Satisfactory for music, but cannot be used for calls, all other sounds are excessively audible (even the music from the supermarket is loud to the caller).

They are amazing headphones, I didn't expect them to be so good for their price, and even at low volume they sound great. I recommend you to buy them

Very satisfied with the product. Fast connection, high-quality sound, very good battery. I have no disconnections at all. In conversation, they hear me very well without any noise. Comfortable and lightweight.

I have had these headphones for about 4 days. They have fallen many times but have not suffered any damage. During a call, they sound like I am right next to them, which is true for me as well. At first, they will fall frequently. Inside the box, there are also other ear cushions, and the instructions explain exactly how to wear them so that they don't fall off. The instructions also include many functions. Simply fantastic. It's worth its money!

I have had them for 3 days now. At first, I hated them because the initial earbuds that they had didn't fit well in my ear, causing them to constantly fall out. When I realized that they have replacements in two other sizes, small and large, I switched them with the small ones and they fit quite satisfactorily.
The noise cancellation is really good to the point where when I have them on at a relatively high volume, all the small noises around me are isolated. The loud noises still exist but obviously it's not a problem as it's good to have some connection with the outside world.
The sound is satisfactory for personal use but not for professional use.
The battery is quite good, so far I haven't had any issues.
I recommend them

The headphones are very good, I bought them for running and when I wear them, I don't have the feeling that they might fall out of my ear because they fit well. One positive aspect is that you don't need to have both of them to listen to music, whichever one you choose connects automatically. They also have very good stereo sound and bass, which I didn't expect. The only thing left to see is if they will withstand the test of time.

I do not recommend them.
I bought them as an "upgrade" from Xiaomi's first wireless earphones, which were fully functional after 2 years of use.
In contrast to this specific product, which did not fit well in the ear from the beginning, resulting in poor sound quality and constant dropping. The problem was not solved even after changing the silicone tips. As a result, I lost one of the earphones after about a week, as it fell and by the time I noticed, it was too late.
But even while using them, I was not particularly satisfied with the sound quality

I use it with a Xiaomi mobile phone. It constantly disconnects and the call sound quality is mediocre to poor. It is better to invest some extra money to get a reliable product.

Very good headphones with clear sound and very strong bass!! First time I get wireless headphones and I am very satisfied. They are worth 100% of their money. My only problem is that they don't sit very well on the ear. If you have a small ear, there is no way they will stay on with anything!!

Excellent product! I am a fan of iPhones and initially I was skeptical, but my friend convinced me to get them and in the end he was right! It connects immediately and the sound is loud and clear! I highly recommend it!
