PinkyPowers posted a review of the Meze 99 Classics on Head-Fi.  It is an interesting review and you need to travers the first sections where PinkyPowers goes off on IEMs.

Pros: Tuning that shines with every device. Comfort. Detachable Cable. What a looker!
Cons: Needs mods for custom cable, or a Meze proprietary plug.
