The new FW3 is a fully integrated, high fidelity true wireless pair of earbuds that combines an independent DAC, professionally-tuned acoustic components, and a high-end Bluetooth chip that gives new meaning to what a HiFi TWS should be. 

A robust core for robust listening AK4332 DAC

The new FW3 features an efficient AKM VELVET SOUND DAC chip— the AK4332. This high-performance chip features a signal-to-noise ratio as high as 106dB, distortion rate as low as -96dB, and a dynamic range up to 102dB.

* The above data are based on tests of the FW3’s internal circuit.

Efficient and stable for smooth operation Qualcomm Bluetooth chip QCC5141

Thanks to the high-end dual-DSP, dual-core CPU QCC5141 Bluetooth chip, the FW3 features exceptionally stable Bluetooth audio and general operation.

*FW3 is Snapdragon Sound certified, ensuring good sound quality.

Unleashing true audiophile-level quality 10mm carbon-based dynamic driver

As a HiFi brand, FiiO will naturally ensure that any of their products feature great sound quality. To achieve this with the FW3, the earbuds feature a high-end 10mm carbon-based dynamic driver. The carbon-based material allows the FW3 to have excellent, quick transient response as well as reduced unwanted breakup leading to less overall distortion – giving the FW3 exception resolution rarely seen in the same class of products.

Attractive and practical Two colors available

The FW3 comes in two kinds of colors, Moonlight white and Interstellar gray, fitting different fashion tastes.

Self-developed technology 
High-quality sound performance
Freely choose between different 
Bluetooth codecs

The FW3 allows users to freely choose the Bluetooth codec they want. Through the FiiO Control app, choose one or more commonly-used Bluetooth codecs, so that the device will not take any low-quality codec as default. Immerse yourself in high-quality music.

GAME READY, THEATER JOY Quickly responds to every change Low-latency gaming mode

The FW3 supports low-latency gaming mode, which is available by enabling the FiiO Music App. The gaming mode significantly lowers the transmission latency to less than 100ms, quickly responds to every action in the game, and instantly locks on the location of the target. In addition, thanks to the Bluetooth transmission with ultra-low latency, the FW3 helps to catch almost every detail when watching fast-paced films, allowing you to be totally immersed in the film. 

Customize your listening to your taste. The FW3 features a 10-band parametric EQ, and for each band you can customize the center frequency, level, and Q/bandwidth of the center frequency. You can DIY a set of “music filters” down to your exact taste.

* Supports control through FiiO Control App. The App functions will be continuously changing, please refer to the latest page.

Every song in your style 10-band parametric EQ

A reliable companion always juiced up 21h long battery life

The fully integrated TWS FW3 not only features high- performance parts that give its excellent sound, but also features impressive battery life. Built into the FW3 is a large 60mAh battery, which when combined with the sizable 380mAh battery of the charging case leads to a total battery life of about 21 hours or more. 

Being easy to use should be standard 4 physical buttons

The FW3 on each earphone features 2 physical buttons, which allow you to more easily operate the earphones by pure touch with zero accidental touches, unlike touch- sensitive buttons. The physical buttons are also placed perpendicular to the wearing angle, making it easier to use without resorting to too much force.

Specially-tuned frequency response Meticulously tuned by acoustic experts

The goal of creating the fully integrated TWS FW3 was to prove that one can create a true wireless pair of earbuds with audiophile-level sound quality. The experts of the FW3 development team painstakingly tuned both the digital and analog components to allow the FW3 to truly faithfully reproduce your music.

“The primary advantage of the FW3’s dynamic driver is on its fantastic reproduction of mid-range vocals, and presentation of rich emotions. The PU material we chose for the diaphragm gasket polishes vocals, and enhances timbre and lushness. For TWS earbuds attaching great importance to sound performance, it can fully unleash high resolution of the light carbon-based diaphragm, making for more clear and delicate string music performance and more relaxed to listen to.”
