My suggestion is to trust UE customer service and don't listen to unqualified people who might suggest X000 hours of brown noise or similar guesswork based on nonblind testing and no measurements. Many posts on a forum and/or expensive equipment doesn't make you an expert. UE - they f-ing designed the things, trust them.

You need to burn-in your own ears more than anything else. If you are coming from any other IEM, the bump in bass on the UE11 is massive. You need to acclimate yourself to it over a few days. It will always remain huge and somewhat overblown (at least to me), but you'll get used to it.
Like others have said, this is the difference between dynamic and armature drivers.
Armature drivers don't require burn in because of their design.
I think there are some thread talking about that here, but I don't have the link

Cables do not burn in, because they have no moving parts. A robot would explain this fact with the old robot saying "DOES NOT COMPUTE". Cables and connector only get (marginally) worse with time because of oxidization and physical abuse from regular usage.
Btw I think I saw that jays put out a new headphone where the cable consisted of a single-crystal, i.e. a perfect Cu lattice with no defects whatsoever. I wonder if the difference with respect to conductivity is even measurable. Maybe it's just that it's much more durable... or maybe defects will introduced by regular usage. When I think about it it's pretty interesting, although probably only from an academic point of view.
