I have had them for about a year and with daily use, they haven't had any issues so far.
I bought them for around 15 euros.
They have fallen countless times, their case has broken, and they have been soaked multiple times (they have fallen into a glass full of water).
They charge in the same amount of time as when I first got them and they last as long as when I first got them.
Mine have the disadvantage that when I speak with them, the person I'm talking to can't hear me clearly, although I can hear them clearly, so I can't use them particularly for calls, but personally, I don't care because I mainly bought them for music and movies.
Maybe mine have a problem, I don't know.
For their price, personally, I wouldn't hesitate, I would just buy them again if anything happened to them.
I haven't been convinced to go for something more expensive.

Δεν πολύαξιζουν. Είναι όντως μία οικονομική λύση αλλά σίγουρα θα σας κουράσουν και θα πάτε σε κάτι πιο ακριβό.
