well i havent gotten any result yet but still believe that i can get one

and yeah ive followed most of the tips and yeah no result and im not here to blame i-doser not for working no cause it worked on my friend with ecstasy and he wa pretty funny
well the question is i bought the doses in MP3 files for puting them in my creative zen micro photo. is it good enough to give me any effect?
and the other question will be that i have koss porta pro "headphones" they are actually kinda open. are they good?, my brother has a creaitve fatal1ty gamer headset is it better? ive tried it and ive felt that it had bader sound than mines
alsoo: where do i find the head and earphones recomended for i-doser? i cant find it anywhere
sry if my english isnt good i live in sweden and have an english teacher whove never said it was bad

thank you for any help and merry christmas hehe:D
