Nmatheis has a review on Head-Fi of the FLC 8S customizable IEM.  The 8S is another in the growing BA/Dynamic Drive segment of hybrid IEMs. NMatheis really liked the 8S


Pros: High-quality, highly-customizable sound. Small. Ergonomic. Built well. Detachable cables.
Cons: Microphonics. Overly tight cinch. Limited tip choices. Very small tuning filters.
