Magnificent sound and shape “Drum” type bass cavity

Based on the drum musical instrument, a bass cavity design was made especially for the new earbuds FF3S. This cavity was specially designed to fully harness and utilize resonances to more effectively bring out the texture of bass notes as well as accurately reproduce the timber of music with surprising agility.

Light in weight with

an extraordinary feel

Aluminum alloy construction

The all-new FF3S comes with a build quality upgrade! The FF3S features an aluminum alloy construction with a matte finish, making for a subtle yet obviously more luxurious appearance than found on its predecessor. Another benefit of the aluminum alloy construction is the lighter weight. Each earbud of the FF3S is only 3.9g, making each earbud 52% lighter than on the FF3. This will give a whole another level of comfort for longer listening sessions, especially those with ears that are very sensitive to weight.

Set out and enjoy the wonders of nature Included silicone wing hooks

Thanks to the open nature of the earbuds, the FF3S is safer and suitable for outdoor activities such as hiking or biking. Thus, standard with the FF3S are silicone wing hooks to help the earbuds stay in your ears. No matter where you go, let high fidelity music accompany you.

Tethered wired headphones with untethered possibilities

0.78mm 2pin detachable cable

FIIO listened to user feedback and equipped the FF3S with a 0.78mm 2pin detachable cable, allowing users endless upgrade possibilities in enhancing their listening experience. Also, an easy-to-feel point was added to the left earbud in order to more easily distinguish between the left and right earbuds for a truly ergonomic design.

Dive deeper into your music Bass-enhancing acoustic flute design

FIIO R&D made full use of the internal space of the FF3S’ housing to fit a bass-enhancing acoustic tube within. This tube extends the airflow path, increases air damping, and improves sound damping to lower the resonance point of the earphones for amazing sound performance. This allows the FF3S to reproduce frequencies as low as 90Hz under normal open wearing [1], and have an effective frequency range [2] down to 42.5Hz for truly deep earbud bass.

[1]Normal earbud wearing conditions without use of a sponge cover.

[2]Effective frequency range refers to the range of frequencies in which the frequency response is not more than 10dB below a certain sound pressure range.

More than just big

14.2mm large dynamic driver

Thanks to its large 14.2mm dynamic driver, the FF3S can release more energy when playing back music to allow for a more clean and natural sound. Experience the vigorous sound of beating drums, as well as energetic dynamics in your music with the FF3S.

Specially-chosen materials

Beryllium-plated dome + PU gasket diaphragm

Good sound not only comes from the size of the driver, but also from the materials it is made of. After many tests by the FIIO R&D team, a beryllium-plated dome + PU gasket dynamic driver was chosen for the FF3S. The beryllium-plated diaphragm is both highly rigid yet lightweight, reducing unwanted vibration and thus unwanted distortion. PU is used for the dynamic driver’s gasket, and its characteristics allow more detailed and textured bass. Not only does the bass come through wonderfully, mid-frequency human voices are lush and the treble also has been greatly improved – with an effective frequency range up to 17kHz. [2] A greater effective frequency range also has the benefit of giving the impression of a larger soundstage.

Capturing all details

Ultra-fine copper-clad aluminum

Japanese Daikoku voice coil

Excellent sound comes from carefully considering all design aspects of the product, including the parts that are not so easily seen when using it. The FF3S’ dynamic driver features an ultra-fine copper-clad Daikoku voice coil. With only a diameter of 0.033mm, the Daikoku voice coil is lightweight and helps to reduce the overall weight of the dynamic driver, allowing it to move faster and further improve treble resolution.

Listening to your heart’s content

2 types of sponge covers included

The FF3S comes standard with 2 types of sponge covers for different kinds of sound – bass-enhancing, and transparent. Pick the ones you want to use for different kinds of music and to your own taste.

Fully equipped

High-purity silver-plated monocrystalline copper cable

The FF3S cable comprises 152 total wires made of high-purity silver-plated monocrystalline copper. This was specifically chosen as the silver-plating improves treble resolution while reducing unwanted sibilance. The sheath of the cable is made of German TPU – allowing the cable to be not only resistant to yellowing and hardening, but also allows for increased cable flexibility so that it is more comfortable to wear and for less undesirable microphonics.

Wide compatibility

Twist-lock swappable plugs

The FF3S features an all-aluminum twist-lock swappable plug design, allowing you to change between 3.5/4.4 mm plugs whenever you need to. This allows you to more easily enjoy the FF3S’ exemplary sound, setting a true benchmark in its class.
