my headphones recently broke, so does anyone know if ipod headphones (older version) can make all the frequencies needed for doses to work?
like, will ipod headphones work for the meantime till i get new headphones?

my friend keeps telling me that its self hypnosis, can you assure me that it is not, he claims the creator of i-doser wrote a book about self hypnosis. im sure it legally says that it is binaural beats somewhere but can you just assure to me it is, no matter what i say he wont believe me. he refuses...

which doses have loud screeching crackling noises, i want to avoid those, they scare me . . .
ive heard that gates of hades and adrenchrome have those but thats all

yeah so if anyone could tell me i would be grateful
