The IEMs in the FiiO FA series, including the new FiiO FA19, are particularly appreciated for their ability to reproduce crystalline highs and mids. This type of transducer is often preferred by discerning audiophiles looking for an accurate and detailed reproduction.

The FiiO FA19 IEMs are equipped with ten Knowles balanced armature transducers. They cover a wide frequency range (from 20Hz to 40Hz) and feature two listening modes (Monitor and HiFi) for a tailored sound experience. Their 3D printed shells, pure silver cable and numerous ear tips ensure optimal comfort and high fidelity audio transmission, all with an elegant and durable design.
