yeah 85% is insane, even if you are not getting a good seal, the sound is still going inside and doing damage. sometimes i'm guilty of pumping the volume briefly too, but I have only experienced ringing one or 2 times since I was in my teens (bass bins ahoy!!)
also, if you are having problems getting a seal with westone IEMs, some of the easiest IEMs to get a seal with, you are going to need some serious luck to get a seal with triple-fi, they are simply the most uncomfortable and huge IEMs i've ever owned. I could only stand them for a couple of weeks, I also got fatigue from the highs. good luck with that; and....turn it down for christ sake and never get an amp
