I've seen reviews for the M9 and M11 without the microphones, but does anyone have the models with the microphones, and what are your opinions on them?
 
Also compared to the M9 are the M11s worth the extra 40$?

I reviewed both the M9P and M11P+ for my site Musical Musings.

M11P+ Review
 
I hope these reviews help you out in making your decision.

Personally, I think the M11P+ IEMs are worth the higher price over the M9P.
