Bringing the driver unit closer to the ear drum, achieves an even more realistic, vivid sound quality.
In order to achieve this in the F4100, we have meticulously downsized the housing with a design consisting of the minimum possible elements. Miniaturized to have a diameter of 5.5 mm, the housing is finished with hard aluminium-magnesium alloy anodic film. This also contributes weight reduction. Final's unique method of using full-range balanced armature drivers across all models recreates bass tones with a fullness you would never imagine from the housing size. The cable is high purity OFC with detachable MMCX connectors.
The earphone comes with an ear hook to prevent microphonics from the cable. This is one of final's proud model, realizing sound quality and ease of use in a higher dimension. It tends to have a slightly
warmer sound quality than the F7200.

You can position the product to be at the back or at the entrance of the ear canal, and change the sound quality by choosing different earpieces.

We have used an ultra small full-range balanced armature driver unit.

We used an aluminium-magnesium alloy for the F4100 housing, which in turn is finished
in a chic black anodic film exhibiting high hardness.

We've included silicone earpieces in 5 sizes and foam earpieces (COMPLY) in 3 sizes. Achieve a perfect fit no matter how large or small your ear canal is. Sealing performance is closely related to how the bass feels, as well as soundproofing performance. This system enables you to significantly change the fullness of the bass or the soundproofing performance.

We've used high-precision MMCX connectors from a famous Swiss manufacturer.

The cable is high purity OFC. The PVC tubing has been chosen for its flexibility and has been finished with a rope-like texture to reduce microphonics.

* The connecting terminal has not been configured with a view to frequent connection and disconnection. Repeatedly connecting and disconnecting the terminal may lead to contact failure owing to wear or damage to the terminal; please ensure that any connection or disconnection is limited to situations of cable breakage or when the cable is replaced with other final cables that are sold separately.
