How much noise leakage is there from having these vented? I'm after something that's easy to put in, comfortable, discrete but blocks noise quite well as I would be using these in an office. Customs and I don't get on that well for some reason so looking for alternatives. I listen to rock and audiobooks out of either a 7th gen classic or clip plus. I also tend to listen to 5-6 hours a day each day.
I thought the same thing so i got the Mrs to listen closely in a quiet room and see if she could hear anything.She could hear the treble on a Electronic album when i had it louder than my normal listening volume and i like dance music loud! otherwise at normal volumes she had to be right up close and she could barely hear anything. a friend tried them on and he listens loud and i could just hear some feint treble.probably a little more than my shures leaked sound but not much.
