The test takes 20 seconds:

Did you find out right?
 
My answer:
I'm using HD650 and got it wrong.
 
 
 
Second test:

What's the highest frequency you can hear?
I notice up to 21kHz in HD650 with X2 volume gain.

Got it right, but would need a bigger sample to be sure. I could hear 19kHz clearly, 20kHz maybe if there wasn't any background noise coming from my room.

I got it right. Listened to the first, then second, then first again. Grado SR80i, modded. The difference is not that great on this test, really.

Got it right, not a HUGE difference, but the pops in the background and the drums distort a TAD.
I can also hear up to 20khz.
I can gear down to about 17 hertz or so....I can FEEL 4 but I cant really say I hear it.

I got it right,,, Though it's not as evident on this song. Depending on the song, it's a lot more evident between bitrate.

Beyer T5p using an Asus Xonar U3 sound card.

I tried a signal generator on my tablet and was able to hear upto around 20khz. But using my laptop setup, my sound card has quite a bit of hiss and I can only hear upto 19khz.

See spoiler for hint, then spoiler inside spoiler for answer. But be honest, guys.
 
 
Listen to the cymbal + drum whenever both hit at the same time. 128kbps will sound like the cymbal just "breathed" out and completely omitted the drum spat.
 
I could hear that very clearly with my setup. MBP -> Fiio E11 -> JDS Labs O2 -> DT880.
 
It's clip #1

I can honestly say without voting that I can't tell the difference.  Not really the best example I don't think, but I guessed wrong anyway.

This.
 
And you don't want to know which pair of cans I'm using for this...
 
Anyways - compression artifacts are a weird deal; some material can be highly compressed and not sound naughty, other material cannot. I'm skeptical of the FR hearing test, due to my equipment, but last I knew my hearing topped out around 14-15k (and that's after lots of exposure to lots of very nasty things).

That was mentioned in the comments, that the tones were not properly generated or set-up. If you have something like Audacity or Sound Forge you can generate a sweep and go with it. Make sure you set the audio output and sample rate at 96k so that it can clear 20khz without a problem (if it's left at 44.1k it will fold at 22.05khz). And no, this isn't the same as having an audiologist do it.

Got the the song part right, but I feel like I'm hearing some kind of background distortion in the test tones so I'm not sure where my hearing actually cuts out.

I got it right using my HD650's.
 
Its easy if you listen to the cymbals. The correct sample is much more detailed and realistic (crisp). The 128kbps one is a bit "fuzzy" in comparison. I wouldn't be able to tell 320kbps vs lossless however.

Got it right with my Monitor 10s. Actually, I found this test to be quite easy. I didn't even have to listen to the whole clip. However, there is another online test, which name escapes me right now, that was pretty difficult.

using SE530
 
the clip was quite obvious imo, but surprisingly i could hear every single one of those kHz things. which just blows me away, id have thought for sure my hearing is damaged.

Looks like it's depending on the software I use. I doubt I actually heard anything past 18kHz, maybe it was only clipping or some noise from the hardware.
