On the audio side, the sound is very good and more than enough for standard use. A good value for money.
The handsfree works well although there was a slight hiss. By cons, to use in a quiet environment.
By cons, sending side, mine happened to me in just a shell with a transparent plastic bag without warranty, nothing is labeled Sony. Clearly, I have no idea if this is not a counterfeit. It's a shame for Amazon not to specify such details.
