Extraordinarily small & lightweight, with a perfect fit & good sound insulation properties. Located close to the wearer's eardrum & being distinctly airtight, this model delivers high resolution, a large sound stage & coherent bass tones.
Bringing the driver unit closer to the eardrum attains an even more genuine & authentic sound quality. In order to attain this in the F4100, we have diligently downsized the housing with a design consisting of the minimum possible elements. Downsized to have a diameter of 5.5mm, the housing is finished with a hard aluminum-magnesium alloy anodic film. This also contributes to weight reduction. Final Audio's unique method of using full-range balanced armature drivers across all models recreates bass tones with an ampleness you would never presume from the body size. The cable is high purity OFC & has a detachable MMCX connector. The earphone comes with an ear hook to prevent microphonics from the cable. It tends to have a little warmer sound signature compared to the F7200 model.
