I actually had an audiogram performed...about 18.5kHz in both ears. Not bad for pushing 40.

I came across this site today for hearing tests if anyone is interested.

Guys I am pretty sure those online tests are fairly inaccurate.
P.S. On the HD800 (and even other Sennheiser models): Even though I don't agree with the tonal balance of the HD800 (hence the mods), I'm still amazed what Sennheiser can do with dynamic drivers. They probably have a secret lab facility with engineers who have been doing these kinds of measurements (and even more) for some time now.
Dood, they do strobed laser interferometry to watch cone break-up real time.
I too am AMAZED sometimes at the level of technical performance of the HD 800. AMAZED!

Too bad they produce too much sibilance on female vocals, and their bass is on the anemic side.
In my experience, it's pretty easy to find speakers which sound great all-around, and there are many choices that fall into the category where it's hard to point to any significant weakness. With headphones, you can always point to some weakness, which is I guess why people keep trying different ones in an endless cycle...

.............................................. The orthos sound compressed and just don't have the dynamic capability, and that aspect is #1 or #2 on my list.
