good choice, economical and reliable.
only negative is the conversation topic where it doesn't have a good microphone and you have to shout more for your interlocutor to hear you.
also in terms of music, it doesn't have very loud volume in all playback applications.

If someone can help me, when I bought them the battery lasts very long, but when I tried to charge them, they didn't charge because the cable that came with the device is not micro USB

I switched from Xiaomi mi true wireless earphones and I don't regret it at all.

POSITIVES

Very good price, I got them for 20€. Decent sound quality, they fit nicely in the ear and have a long battery life.

NEGATIVES

Instead of having type c, they have micro USB for charging and sometimes it takes a little time for my phone to find them.

Are they worth it? Definitely

I have been using them for 2 years now without any problems at all. Good sound for music and calls. 20-30 minutes of charging and they last for 2 hours. It's just a matter of getting a good functioning pair.

1) They have a pretty good sound for music.
2) and for speech, they are satisfactory for the 20 euros they were purchased.
3) satisfactory battery.
4) comfortable fit in the ear.

The 2 stars are exclusively for the connection time.. (many times I don't have enough time to answer calls until they connect.. And I have devices with Bluetooth 5.0) and for the disconnections.. To listen to music without interruptions, you have to be still like a statue and the phone as well..
Update: 5 months after purchase.. Without much use.. (5-10 hours per week) suddenly the right one stopped charging and maybe the case doesn't show the remaining battery correctly.. Terrible
