beyer 1990 PRO not being HI RES certified

[The Computer Audiophile]

First, I wouldn’t let it bother you at all. I don’t think it really matters if a product has this made up “certification.”

 

Second, check the frequency response of both headphones. Do the certified phones have a wider response than the uncertified, say above 20 kHz? If yes, then this is the reason for the high res “certification.”

I just checked the Beyerdynamic page. The DT 1990 Pro plays up to 40 kHz, well into high res territory. 

 

Don’t worry about the lack of fake certification.
