I have a pair of AKG Q-701 that I've had for a year or two, not the greatest things on the market but I like to think they're better than average. Certainly the best I've ever had, anyway.
I noticed today that on the sides in little bold black print near the Made In Austria bit, it says "Reference headphones Q701". I don't remember the packaging mentioning anything about them being "reference" headphones, and I did a few minutes of research on the term before coming here, but I'm not totally clear on what it means, if anything. Is it just a marketing thing? That seems unlikely to me because you wouldn't see it til you already had the things opened and set up. But I'm also a little hesitant to believe that these could be reference cans on any professional level (they're good, but a pro would certainly have better).
So what does it mean, if anything?
