Frequency response of required headphones...?

The Sennheiser RS 130 Wireless Surround Sound Headphones are the headphones required as said on the i-doser website. They have a frequency response of 18 Hz to 21 kHz frequency response. However, some of the doses (such as elta) go also as .5 Hz.
How is it possible for these frequencies to be picked up?

Because theyre binaural beats and there is a specific science behind them. say you play a 500hz tone and a 510hz tone at the same time... the two tones playing together produce a subsonic 10hz tone. thats pretty much how it works.

What? That wasn't the question. You've just explained how they can make the frequencies, not how they can be picked up.
I too am having a very hard time finding any headphones that can go even close to 1hz. I have some earbuds that can respond to 6hz, which I'm guessing is good enough for most things, but most headphones I've seen only go as low as 20hz. This is only low enough to effect beta brainwaves.
Correct me if I'm wrong though.

Yes, you aren't getting it. It's the difference between two tones played between your two ears. No dose would require headphones that can reach a 1 level.

Ahhh, thank you for that. There seems to be a high volume of people asking whether or not a certain pair of headphones would work. Is there a guide or somewhere that would help determine if a pair of headphones would work?
If not, I think that would be a great idea for a sticky thread. If so, well, disregard this and I'll erase it if I find it.

We only really recommend the headphones that are used by I-Doser engineers, and those are available from I-Doser.com

ok well if the admin could answer this, my headphone's freqency response is 16 to 21. yet adrenochrome crackles like hell around 80%. Is this normal? because untill this point this is my favorite dose. When i close my eyes i will sometimes get a sudden flash of light and feel like something is going to attack me, scaring the hell out of me, then i opened my eyes in fear, and my light fixutre flashed and disappeared, honestly, then when i closed and opened my eyes to see if i was retarded, it was there again.
