Dang it - there is TOO a burn-in for armature IEMs (at least for Shures) (I think)

I agree that better-resolving and more neutral equipment allows one to hear burn-in changes more readily.

Less resolving equipment and source material are muddier and differences are more difficult to detect.

Of the new headphones I've had, the L3000 exhibited the most perceived changes, whether due to actual burn-in or not.

Of course they are muddier, but the delta between "new" and "burnt in" will be the same.

Why would you think that a "non muddy" driver would change more with "burn-in?"

I have logged a lot of hours on my current pair of e4c's, and have started noticing a hissing coming from both my ipod and laptop out. I don't have an amp or line out to correct this, but I did try a new pair of e4c's in both sources, and the hissing was much less. Is this a degradation of the iems, becoming more sensitive or "burn in"?

I want to send in my current pair for warranty repair, the hissing is getting quite annoying.

I own the E4s and owned the E3s and noticed no burn-in; and this is coming from me, a guy that swears that IÇ- and LS-cables (if covered in teflon) have a really noticable burn-in time.
