Most headphones have the high end rolled off below 20khz because it can be harsh on the ears with the driver so close to your ears. My DT9990pro are not rolled off and have upper extension to 35khz. The reason for upper driver extension is to make sure all frequencies are reproduced. DT990pro is designed as a studio headphone so need to reproduce all frequencies, that's why some people don't like them.

Is that a typo? I think most can hear 12k unless you are deaf. It's when you get above 17k that you have good hearing.

Maybe going beyond the range of what the drivers are capable of?

Wow, how old are you? If you are over 30 then I would classify you as having golden ears.

Yea, deeper bass and brighter highs. DT990pro are a good example of that, 5hz - 35khz. But you have to look at their decibel level across all frequencies though, the flatter it is the better.

are you serious? That is so messed up. It's like those bark control devices for dogs. I mean if they don't want youngens around, fine, but use a broom or something.

Any bay area, California head-fier's here who are really bothered by the noise on Bart (subway)? When it goes under the bay, there's this really loud howling noise, which I'm sure is causing hearing damage to everyone on the train. But maybe it hurts me cause I can hear 20khz. I always cover my ears and everyone is like what's this guy on about? Either that or if I wear my K81dj's it's fine.

Or play Celine Dion 24/7 on Radio Shack outdoor speakers.

Yes, I am very serious. I read the article about a year ago. Think it was maybe a BBC article but can't say for sure now.

Ever heard of city hum that only some people can hear? Low frequency hum that drives some people nuts and only some cities exhibit this phenomena. I think Vancouver, B.C. is one of them.

I couldn't hear past 17k. I think working in a carpentry shop for a few years helped. Gonna use earmuffs 24/7 from now on

I used to work in printing and the presses can get very loud. For the first 6 months I wore nothing and then finally had a pair of custom ear plugs made for me at the companies expense. That's what you need to get because they block sound better than ear muffs and are much more comfortable to wear for long periods. They make molds of the inside of your ears and then make the ear plugs from those.

Thanks for the kind tip But ear plugs would be to much of a hassle (in terms of hygiene) in a dusty environment. Tried to use some in ear canal phones at work but gave up after a few days..
