there are apps for smartphones that measure noise in decibels, for example SoundMeter , (i also had similar for symbian phones).
and when you have new headphones, just put them close to iphone's microphone and play some test tones (for example 30hz,40hz,1khz...), write down db figures from your app. then repeat precisely the same thing after some time (for examlpe 100 hours).
if there is significant difference between db scores - physical burn in exists.
