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 aluminum-magnesium alloy anodic film. This also contributes to 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 models, realizing sound quality and ease of use in a higher dimension. It tends to have a slightly warmer sound quality than the F7200.

Housing design that minimizes the distance between the ear drum and the driver unit.

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.

You can also change the position of the earpiece. Enables the sound output to be at the very front face of the earpiece. This is also a way to adjust sound quality. With the sound output at the very front, you will be able to feel the sound being transmitted directly.

Full-range balanced armature driver unit

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

Aluminum machined high rigidity housing

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

Choice of 2 types of earpiece

We've included Silicone earpieces in 5 sizes and foam earpieces 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. The foam type in particular has Soundproofing performance similar to noise cancellation ear pieces.

MMCX Connector & Original high purity OFC cable

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.

Ear hook

The F series comes with an ear hook to reduce microphonics. Conventional products of the same type are slightly bigger in order to accommodate a range of ear sizes. This not only makes them stand out visually, it will also take you considerable time to get used to how they fit. As a result of re-investigating what the key is in attaching the ear hook, we discovered that making the ear hook smaller than normal, and doing away with metal or resin wires, meant the shape could fit more People's ears.

Newly developed carry case

The carry case for the housing has also been newly developed.

The earphones themselves are gently secured between thin domed silicone and a lid. This case is designed such that the cable is wrapped around the perimeter of the case and the plug is stored in the base compartment separate from the earphones. Cases that fix the earphones neatly in the same position might look good, but your cable will break more easily if it is stored in the same position every time. Our system satisfies opposing demands simultaneously? it takes into account damage that might be caused to the earphones themselves while preventing your cables from breaking by making sure they are not always wound into the same position. The resulting size fits in the palm of your hand, is lightweight, and easy to carry around.

Safe fit ring

The earphone comes with a safe fit ring so you can use your Silicone earpiece safely.

* When using the Silicon earpieces, please ensure that you mount the accompanying safefit rings. Using the Silicon earpieces without the safe fit rings may result in the earpieces changing position and the tips of the housings protruding from the earpieces, which may in turn injure the ear canals.
