As I stated in my previous e-mail, if the headphone is designed to be used only with the associated car system then I believe it is most likely exempt.
If, as you stated, it can be used to play music from any type of mobile player, like a phone over Bluetooth, then most likely must comply. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of John Woodgate Sent: Friday, March 29, 2013 3:27 PM To: [email protected] Subject: Re: USA Lab for Headphone Sound Pressure Level Test per EN 50332-1 In message <cb4d5768bea42049b063ebe16e819bf20ff3f...@bluprd0811mb414.namprd08.prod.o utlook.com>, dated Fri, 29 Mar 2013, "Tyra, John" <[email protected]> writes: >The sound pressure requirements are also for standalone "listening >devices" not sold with a specific portable player and not only for >portable players and associated headphones. 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.
