This is why they have you select your specific headphone model, and only support certain models. They are compensating for the characteristics of what you are listening with.
Its not going to be perfectly accurate, but should get you into the same (or possibly better due to lack of noise/business) ballpark as auditioning in a store.
How can a set of headphones replicate the experience of hearing and feeling sound through a set of speakers?
Sitting in front of a set of speakers is a totally different experience than wearing headphones. With a decent set of speakers, you can feel the sound. There's some nice headphones out there, but they can't replicate the way some good bass feels through a set of decent speakers.
I can see the comparison system working alright for some things. It's just not a replacement for listening to something on hardware and if I were out to spend some money on a good set of speakers, i'm going to want to listen to them in person first.

All hearing is 'feeling the sound' - that's what sound is a, a feeling of vibration of air.

So it's got value?

So it's not perfect? Why does everything have to be perfect?
I mean, it might be useful for comparing headphones while using headphones within a similar range, not much else. The car systems, home speakers, surround speakers etc. Not so much. So most of the company's inventory based on my browse through the site.
