Tried the UE 900 for a while at a store, it sounded like a TF10 with better clarity and detail. It has the same UE sound sig which I love. This is coming from an inexperienced audiophile, but it certainly sounds like an upgrade over the TF10s. Now if only I have the money to get this IEM.. :(
Edit: Not sure if I like the braided cables, though. It seems to get tangled easily and is very hard to untangle once it gets tangled.
