Tobias89 at Head-Fi posted a review of the FiiO EX1 IEM.
Pros: Rather balanced signature and is very detailed, which is rare at this price point. Good build quality. Cheap, excellent bang for buck.
Cons: Poor isolation due to semi-open design. Springy cable that results in some microphonics. Some treble harshness. Identical to Titan1 (except cable)
