i used my er20s last night
they either kick serious ass or i didn't use them right
i had them in and you could hear everything great, however when i took them out there was little to no difference in volume
so i either have ears they don't fit good and they were not really blocking the sound correct or they really do make foam ones seems like crap
any ideas?? i just thought there would be more of a volume change like when you remove foam ones
