Final Audio – FI-BA-SS Earphones


The Final Audio – FI-BA-SS Earphones are the flagship of the Final Audio balance driver series.  These are designed for stage performance and hi-fidelity audio listening.




Product Description

With Final Audio’s special “BAM Mechanism” design, air movement inside the housing is optimized, allowing the FI-BA-SS to produce deep bass without the variance of distortion and muddiness found in many earphones. The design theory of this breakthrough earphone rests on a single driver directly connected to the circuit, and uncomplicated by the presence of other drivers. The FI-BA-SS is a handmade product, made by Japanese sound engineers with a full-focus on ideal sound with zero compromises. This is Final Audio’s flagship balance armature earphone series and their premium model for stage and hi-fidelity use.
