for me they didnt work to put them under my helmet, but you can put your helmet on and have them go around the back of your head (depending on your helmet), then put them under your helmet straps so they stay down
Icon twos are better in general cause they have a better cord) braided fabric stuff instead of rubber, and they have the felxable part over the head, but Icons fit under a helmet better - if you're not wearing a helmet go with the icon2s.

my helmet that i have is a bern (which ever one has a brim and no vents) and it is so big that i have to wear a beanie under my helmet or it bells like a bucket a shakes around. so do you think the icon would fit under it. if any one has an estimate of how thick the headband wire is i could test it. cause i want the level 1 blackout or the poorboyz one. thanks.
