I think its better to have it in both ears because mine fluctuates from both to one and the sound changes, when its only in one It can really piss me off, because it feels so unbalanced. But seriously who does that 5 times, Its like they don't think and act like complete idiots, I know and I have met so many stupid people who love to make noise and I usually pay for it. A fan like sound, is interesting do you ever have pitched sounds and then have it change pitches and then settle?
