Kevingzw has a review of the FLC 8S IEM on Head-Fi. As I mentioned in the preamble of another review, these are a hybrid 2-BA 1-dynamic driver IEM. The interesting difference with other hybrids is that it is tunable with 36 different configurations.
Pros: Unbelievable Coherence, Distinct Airiness, Endless Customization/Tunable Options, Lightweight and Solid Construction, Aluminium Carrying Case
Cons: Tuning Ports/Filters are fragile, Tedious Tuning
