Me too. I'm thinking as long as you stay on the outer canal area, around where tri-flange IEM tips end, you should be fine. I think what often happens is people get over-zealous and go too far or rub too hard. It's like brushing your teeth- you actually can over-do it. I think if my inner ear started to hurt and it didn't go away within a few days, I'd seek professional help. Same thing with the eyes or any other part of my body I value greatly. It's too much to risk playing doctor. Heck- if I were a photographer and I lost one eye, I could still go on. But if you lost hearing in on ear, in this hobby that would suck to say the least. And while you're at the audiologist, you might as well get some impressions made for customs too!
That's because photos are in 2D Lol.
Btw while we're on this topic what causes "ringing" in ears? after loud music I usually don't even notice it (except for a club or a concert etc.), but if I go away to the countryside or some place really quiet, then I notice my ears are ringing (from listening to music with IEM's).
Also right now while my right ear is blocked I notice my right ear is ringing, but my left isn't, is that because my right ear is in a nice quiet place now while the wax is blocking more sound than usual from the outside world? =P
Sorry for OT from insects but I find it strange.
