I give two stars because although they are cheap for Bluetooth, they did not serve me for the purpose I wanted them for. The music and the caller sound good to you, but the other person hears you as if you are in a well. Every time I tried to talk on the phone, everyone asked me to disconnect the headphones. I also had the wired ones from Defunc, which are much much better.

They have very good and powerful sound and good fit. I consider that for the money they cost, they are flawless. All my callers can hear me clearly and loudly and so can I. Very good battery life as well. They are one of the best headphones I have purchased.

It is the second one I am getting because I lost the first one.
In call quality is very good. They hear me well and I hear well.

The sound quality in music is average.
In the 20€ range and for those who do not want to spend a lot, I consider it a fair choice.

It is one of the best headphones I have ever used! The sound quality during calls is clear and strong. For music, it sounds very clear and loud, competing with Akg. They have lasted for over a year and not with the best handling. The shape of the headphones may not be liked by some, it does not fit as well as earbuds.
