When music playing I don't hear a thing from what my really loud friend says right in front of me. I think a better way of judging the seal is bass. If the bass is not there to begin with, then it is very likely that the person does not have a good seal. All I was trying to say was to give people some peace of mind when they can hear stuff when there's no music playing.
