Hello, everyone.

I actually have these:

In the FAQ there is said the folowing: "Please check I-Doser.com. We list the exact headphones used by I-Doser scientists when designing doses, and they wll give you the best experience with I-Doser brand products.". Where is that list?I haven't managed to found it on i-doser.com.

Alpha band means frequencies 8 to 13 Hz frequencies.

If we look at characteristics of casual headphones, available at affordable prices we can figure out that most of them are not capable for frequencies lower than 20 Hz. Only professional Hi-Fi models like Sony MDR-CD900ST (5 - 25K Hz) and Sennheiser HD280 (8 - 25K Hz) have alpha band inside their band.

If we look at Wikipedia for human ear characteristics, we can figure out that "Humans can generally hear sounds with frequencies between 20 Hz and 20 kHz".

So the question is how can the "Alpha" "dose" even produce any hearable sound?

And if it works in some way that does not require actual 8-10 Hz sound playback then should one buy expensive Hi-Fi headphones to "doses" to work as they are meant to?

Are Philips SHP805 (10 - 25K Hz) meant to work fine with i-doser?

The doses can work with regular headphones. Probably not as effectively, but they'll still work.

My guess with the sounds would be...that's just to hear it. I believe the human ear can be affected by sounds it can't hear. Probably only within a certain range of Hz that you can already hear.

Again, that's just a guess...

i think the distance between the sounds is the frequency. for example, if the sound was 100 Hz in the left ear and 105 Hz in the right, you would hear a 5 Hz beat. it never really goes below a 20 Hz frequency

So any headphones should work fine in this case. Even those bought for 4 dollars.

yes, but better quality amplifies the dose. you can tell the difference between the i-pod earbuds and my nice headphones easily
