on bb im runnin 100 too like bf1983 / ipod im at -7 to -10db rockbox'd or roughly 70 -85 percent usually. lol i like my music loud 

So it looks like ok I guess.esanthosh said:I don't know about M1, but that's the rough range I listen too: -28 to -18 for almost all IEMs, and most of them around -25. I listen in a quiet environment almost all the time.
I cannot hear any tone when i click on the start calibration button. tried both headphones and speakers. something wrong or what?esanthosh said:To test your hearing (and to find out if there's any actual hearing loss), use this : Test Hearing
(Thanks to: dfkt in this abi thread - I has golden ear??? - Random Chat - abi>>forums)
But, the headphones / ear phones used might give a skewed response. I used PFE and could hear the 20 Khz tone at lower than "normal" levels (click Print at the end of it to see normal ranges). How come? May be haraakiri can do the test and see if he hears it too!
