So I just got in a pair of JVC FX850s.  Bass is good but my GOD the trebs are on fire!  The trebs are so hot in fact I couldn't tolerate even 2 minutes of listening before major fatigue settled in.  
 
Anybody have this happen to them??

Trebles do sing for 850's, but if you find them fatiguing, then you can tame them somewhat by using comply tips. As for me, they are not that fatiguing.

Hmmm this is really concerning 

 I've read a lot that the bass was great and clarity was great but nobody really mentioned it was slightly silibant... Might be my ears being too sensitive to the higher frequencies...
 
Might have to try the comply tips and see how it goes...
 
Did the trebs change at all after burn in?
