Great sound and shape - "drum" bass chamber

Inspired by the musical instrument drum, a bass cavity has been specially developed for the new FF3S headphones. This cavity has been specially designed to take full advantage of the resonances and better bring out the texture of the bass tones, accurately reproducing the wood of the music with surprising agility.

Lightweight with exceptional feel - aluminum alloy construction

The brand new FiiO FF3S comes with an improved build quality. The FF3S features an aluminum alloy construction with a matte finish, giving it a subtle but much more luxurious look than its predecessor. Another advantage of the aluminum alloy is its lighter weight. Each FF3S earbud weighs just 3.9g, making them 52% lighter than the FF3. This offers a whole different level of comfort for longer listening sessions, especially for those whose ears are very sensitive to weight.

Included silicone wing hooks

The FiiO FF3S come with silicone wing hooks as standard to ensure the earphones stay in your ears. No matter where you go, let high-fidelity music accompany you.

Wired headphones with untethered possibilities - 0.78 mm 2-pin detachable cable

FiiO has listened to user feedback and equipped the FF3S with a detachable 0.78mm 2-pin cable, giving users endless upgrade possibilities to enhance their listening experience. In addition, an easy-to-feel dot has been added to the left earbud to help differentiate between left and right earbuds and ensure a truly ergonomic design.

Immerse yourself deeper in your music - Bass-boosting acoustic flute design

FiiO's R&D department has fully utilized the interior space of the FF3S housing to incorporate a bass-boosting acoustic tube. This tube expands the airflow path, increases air damping and improves sound attenuation to lower the resonance point of the headphones and achieve amazing sound performance. As a result, the FF3S can reproduce frequencies of up to 90 Hz in normal, open-back wearing [1] and has an effective frequency range [2] of up to 42.5 Hz for truly deep earphone bass.

[1] Normal wearing conditions for earplugs without the use of a sponge cover.

[2]Effective frequency range refers to the frequency range in which the frequency response is no more than 10 dB below a certain sound pressure range.

More than just big 14.2 mm dynamic driver

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

Specially selected materials - beryllium-coated dome tweeter + PU sealing membrane

A good sound depends not only on the size of the driver, but also on the materials it is made of. After numerous tests by the FiiO research team, a dynamic driver with a beryllium dome and PU seal was selected for the FF3S. The beryllium-coated diaphragm is very stiff and at the same time lightweight, which reduces unwanted vibrations and therefore unwanted distortion. PU is used for the seal of the dynamic driver, whose properties enable a more detailed and structured bass. Not only does the bass come across beautifully, but the mid-range frequencies of human voices are also rich and the treble has also been greatly improved - with an effective frequency range of up to 17 kHz. [3] A larger effective frequency range also has the advantage of creating the impression of a larger sound stage.

[3] The effective frequency range is the frequency range in which the frequency response is no more than 10 dB below a certain sound pressure level.

Capturing every detail - ultra-fine copper-clad aluminum voice coil made from Japanese Daikoku

Excellent sound comes from careful consideration of all design aspects of the product, including the parts that are not easily seen in use. The dynamic driver of the FF3S features an ultra-fine copper-clad Daikoku voice coil. With a diameter of just 0.033 mm, the Daikoku voice coil is very light and helps to reduce the overall weight of the dynamic driver, allowing it to move faster and further improving treble resolution.

Listen to your heart's content - 2 types of sponge covers included

The FF3S comes standard with 2 types of sponge covers for different sound types - bass boosting and transparent. Choose the covers you want to use for different styles of music and to suit your own taste.

Fully equipped High-purity, silver-plated monocrystalline copper cable

The FF3S cable consists of a total of 152 cores of high-purity, silver-plated, monocrystalline copper. This was specially selected because the silver plating improves the resolution of the treble and at the same time reduces unwanted sibilance. The cable's jacket is made of German TPU, which not only makes the cable resistant to yellowing and hardening, but also allows the cable to be more flexible, making it more comfortable to wear and reducing unwanted microphonics.

Wide compatibility - interchangeable twist-lock plugs

The FiiO FF3S is equipped with an all-aluminum interchangeable twist-lock plug, allowing you to switch between 3.5/4.4 mm plugs at any time. This makes it even easier to enjoy the exemplary sound of the FF3S, setting a real benchmark in its class.
