I'm not challenging your statement, but just questioning here for my own edification:

Is there any source you could listen to through headphones that produces sound in the 80kHz range? Even CD's are recorded with a 44kHz sampling rate IIRC...so they can only possibly capture sound up to about 22kHz. Not sure what you'd plug your headphones into that would provide more sound than that?

On the other hand...if it's just the driver that has such a high frequency response, then I could see it more accurately producing the 20kHz sound (you know, with .00001%THD instead of .0001%).

Yes, but in live sound applications, there will often be the higher harmonic structure above 20Khz that these headphones will be able to reproduce. Though the open/closed combined design is not likely to isolate the solo sound source well enough.
