The companion standard, EN 50332-2, which applies to signal sources and headphones separately, is also referenced in the Note. BUT PLEASE NOTE, it is a NOTE, giving information; there is NO requirement to apply either standard. In fact, both standards are highly controversial and steps are being taken to create a more satisfactory situation. Meanwhile, I recommend that you include in the instruction book for your product, advice about the subject, along the lines at this Microsoft web site, under 'Zune and Zune headphones': http://www.zune.net/en-us/support/productguide.htm#safety -- OOO - Own Opinions Only.
