Some people bought something else or are exaggerating for no reason.
1) Charging, every 2 days and it works for ten hours and then I turn it off.
2) Distance, at 6 meters I play music and it plays without any problem.
3) The sound is excellent, nice bass and treble that I didn't expect. For the record, I deal with sound and I can understand what is good and what is not.
4) In calls, they hear me clearly, I never had a problem.
5) They fit well in my ear, now this is a matter of everyone's anatomy.

For its price, it is what it should be.
