It has an app that modifies sound, hearing, and literally everything, including noise isolation. It works on Sony 4 and 5, as well as on PC. I guarantee you that the sound quality is excellent—I bought it from Jarir. The settings, once adjusted, work on the Sony device. It also comes with a cable for the splitter, although I didn't take a picture of it. I bought it for 999 from Jarir.
