My first headphones from Sony. Due to noise cancellation or because of the generally good sound - I now hear sounds that I have not heard before Noise cancellation is good. You can sit next to people, a conversation will be heard a little, but you can concentrate: it jams quite well in my opinion. Convenient application. It's cool that there is automatic switching of the noise reduction mode (install applications for the phone): went outside - ambient sound, you go in transport - noise reduction to the maximum You can also switch the language there if a model with Chinese voice acting has arrived) I saw something about codecs in the reviews: there were no problems with connecting to Linux (Ubuntu), or to Windonws 10 I recommend
