Extremely small and lightweight, with a perfect fit and high sound insulation properties. Situated close to the wearer's eardrum and being highly airtight, this model delivers high resolution, a vast sound stage and clear bass tones.
Bringing the driver unit closer to the ear drum, achieves an even more realistic, vivid sound quality. In order to achieve this in the F3100, 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
a hard aluminium-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. The earphone comes with an ear hook to prevent microphonics from the cable.

The entry model for the F series, this earphone realizes sound quality and ease of use in a higher dimension and is tuned to emphasize reproducibility of lower tones compared to the F4100.

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.
Full-range balanced armature driver unit
We have used an ultra small full-range balanced armature driver unit.
Aluminium machined high rigidity housing
We used an aluminium-magnesium alloy for the F3100 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 (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.
Original high purity OFC cable
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.
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 rings (for silicon earpieces, for foam earpieces) so you can use your earpiece safely.

*Using the 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.

How to wear the earphones
Check the L (left) and R (right) designations on each bush to distinguish between the right and left ear pieces (there are also protrusions at the bottom of the L on the left bush and on the reverse side of the same bush, so that left and right are easily distinguishable even in the dark). Holding the connector, fit the ear pieces into the ears using a slight twisting motion.

It is usual that a person's ears differ from left to right in terms of audio canal length and shape. Usually, fitting earphones in the same position in both left and right ears results in a discrepancy in the distance between the ear piece and the eardrum; this changes sound quality, and effects a slight sense of discomfort. With the F series, by changing sound quality through the positioning of the ear pieces in the ears, it is possible to avert this sense of discomfort between right and left. While playing music, move each ear piece around individually to find the fit that reproduces the most favorable sound for you. This is the best position for
the ear piece. At first, this may take time, but once you have set this position, your body will be quick to adjust and remember the audibility and the feel of the fit, and it will be easy to fit the ear phones into your ears following this.

You can also change the size of the ear pieces that you use; fit S or SS size ear pieces deep into the audio canals; insert L or LL size ear pieces just inside the ears; change the type of ear piece from silicon to foam and compare the two. Find the size and type of ear piece that delivers the best sound for you.
Sound quality reviews
Clear vocals and delightful crisp low frequencies that seem to cheerfully bounce along are characteristic
of this model. Also well-balanced, it has a soft sound and makes for extremely easy listening. Since the low frequencies are robust, try using this product for pop or rock music. We think you'll be surprised by the size, the weight and the sound produced by this model.
User reviews
High frequencies are full of life, but not so much that they are grating (strident); you can clearly distinguish cymbal hits and there are ample trailing notes. Piano attack is also solid.
Low frequencies are not too thick and moderated, and there is a sense of power to the 16-beat roll of the bass drum, without it weakening.
Cost performance is fantastic.

You feel a sense of volume and quality bass tones you wouldn't believe of a single BA. I think that this is an easy-to-grasp-point in terms of the direction of sound production between this and the top two types. I recommend these earphones to people who often listen to rock music. This model definitely does not lack in quality compared to the higher-end F7200 model, so I was really surprised by the product's cost performance.
