It appears that John Tyra was explaining that 60065 and 60950 have their own requirements specific to headphones and that they reference the 50332 standards to be used as the test methods. If that's the case then I believe that the scope of the method (50332) is irrelevant.

How do you reconcile that with this explicit statement on the web page that was cited by Kazimier Gawrzyjal: This Part 2 of EN 50332 specifies methods of measuring the matching values for the use of personal music players and headphones/earphones defined for the use with those... No way is a car audio system a 'personal music player'. I would advise GREAT caution in attempting to widen the scope of the standards by inference, because we will get back to everything, including desktop computers, being considered 'portable music players'. -- OOO - Own Opinions Only.
