The case is definitely superb (if you want something a little larger than you typically need for an IEM).
This is why the case is so good. I've got a splitter, S1, and T90 on one side. On the other I have the ClarityOne, FX3X, and a bunch of extra tips. My other case holds a spare T90, J+- Woodies, and the Samsung Nexus S.
