I have had them for a few days. They have a nice design and are lightweight. The build quality seems good, but I will have a better opinion in a few months.
Until now, I have been using wired headphones, mainly JBL, because I want good music performance. I was looking for JBL headphones in the 50-60€ range and these came up, which review sites rated as equal to the 60€ JBL headphones. So, I took the risk and decided to try them out for the first time, to see if they would suit me.
They fit perfectly on me, without bothering me, and they stay securely in my ears without falling out. When I wear them, they block out about 30% of the ambient sounds. Even in noisy environments, they isolate and have no problem.
As soon as you take them out of the case, they automatically turn on and connect to your phone. When you put them back in the case, they turn off, start charging, and disconnect from the phone's Bluetooth, so the phone goes back to using its own speaker.
The case has a specially designed slot and magnet that pulls the headphones in and puts them in place for charging. It has indicator lights for the charging status on both the case and the headphones.
Its microphone works perfectly. I am heard very well.
The SOUND is clear in the highs, but the initial impression in music was disappointing. Clear, but the bass... nothing. I activated the bass in the built-in EQ and it improved somewhat, but still not satisfactory because the other frequencies became muffled. Finally, I went into the EQ of the mobile app and with the right settings, the sound became PERFECT, on par with a good JBL, with very strong bass and clear all frequencies. Conclusion, the headphones have the potential, but they need adjustment for music.
BATTERY, it worked for 3 days with about 2 hours of use each day for music and did not show a low battery signal. It charges with any regular USB, with its own built-in connector.
CONS, but not significant: 1. When you want to take them out of the case, they don't have a "handle" somewhere in their shape to grip them, and as the magnet pulls them in, they slip. 2. The volume reaches high levels, but I would like it to go even higher, so that when a file is recorded at a low volume, you have the option to increase it.
OVERALL, for the 20€ I paid, it is an INCREDIBLE value for money purchase.

The above still holds true. From use, I have additionally noticed the following:
1. The TOUCH function, for beginners, has a problem because you cannot hold them loosely in your hand. They touch and execute commands and settings uncontrollably. Only from the case to the ear and vice versa! On the other hand, this protects you from carrying them outside the case and losing them! If I buy them again, I think I will prefer ones without touch function.
2. Since it does not have "Microphone Noise Reduction," when you speak (e.g. on the street) and there is noise or wind, the person you are talking to does not hear you well.
3. The headphones, in the end, come out easily if you put your finger in the slot and push them a little.
Nevertheless, it remains an excellent purchase. The battery never lets you down and you charge it after days because you are tired of waiting any longer....
