I understand your point AnakChan and my point still stands. Listening at those volumes is indeed above 85dB.
If you got an iphone or maybe even android device give "etymotic awareness" program (free) a whirl. It'll tell you what you need to know. I just tested it out on my iphone and indeed at 40 volume it is hitting around 100 dB on the 1Plus2! Slightly under it. Raise it up to 45 volume and it's going over 100 dB! (RWA AK100 and Tralucent 1plus2 IEMS). At around 31 it is still around 85 dB sometimes goes over it. But settles around 81 dB average. Still 31 is a bit loud for me but I'd be able to listen to it comfortably for a little while anyways. Listening at around 27 which would be my ideal listening level in terms of louder listening volumes, maxes out depending on track around 85dB but stay generally around 75 to 80 dB. Listening at 21.5 (which is my ideal general listening volume) stays around 70dB average and goes under that.
Listening to the Studio V on volume 6 averages around 75dB and spikes at times to 85 db. I generally listen at volume 5 on the Studio V which is slightly less. My point is listening at such levels (that is 85 and above) will damage your hearing in the long run if the damage hasn't been done already.... I found the information out from Planx :). Gotta love Planx :P.
If you have an iPhone, download the free app Awareness! from Etymotic. You can easily measure your dB by placing the IEM on the mic on the iPhone. I can say it's pretty accurate and my volume ranges from 80-85dB. 90 at most when the song gets a bit chaotic in terms of heavy rock or bass.
You could be right but that isn't the debate. No one is questioning if 85dB is acceptable or not. Sitting on the sidelines, you're talking about apples and Toad's talking about oranges.
