You sound good and your conversation partner hears you well. However, it is heavy and as someone wrote in their review, the three buttons it has on the side, close to each other, are not convenient; when you get a call, you get confused about which button to press

very good quality and great battery life in the specifications it says that there is no Microphone Noise Reduction I would say that in the car at 100kh and with the windows open without the noise being heard by the interlocutors, the only negative is that the sound is a bit weaker in the earpiece compared to others I had. I will compare it with others if it lasts more than 1 year I will buy it again.

Poor battery life (2 days standby).
Poor ergonomics (the call button is hard to find among the volume buttons, the microphone is on the opposite side from where it should be).
Average sound during calls (always making sure the microphone is facing the right direction).
Its size is noticeably larger than most similar products.
The only positive is the satisfactory (at least seemingly) build quality.
I do not recommend it for any reason.

very beautiful and quality with soft plastic that withstands drops, although I ordered the black color I was sent the white which is much more beautiful the RGB light ring is fantastic as well as the indication the vibration is insufficient. Usually similar ones I had do not last even a while this will show.
