Product Description
The best of all worlds - Fully integrated hi-fi TWS solution
The FW5 combines several of FiiO's cutting-edge technologies into a fully integrated, high-fidelity wireless solution. It is one of the first TWS headphones to integrate a high-end Bluetooth chip, a high-performance DAC and a carefully designed audio circuit to deliver a major leap in quality across the board. Let the FWS show you what TWS' new high-fidelity earphones are really capable of.
Hearty Robust - Independent AK4332 DAC
A true wireless headphone must offer high fidelity! The FW5 contains an efficient AKM VELVET SOUND DAC - the AK4332, which boasts powerful decoding capabilities. This chip achieves a signal-to-noise ratio of up to 106 dB, a distortion of only 0.0016% and a dynamic range of up to 102 dB.
More throughput - Qualcomm QCC5141 Bluetooth chip
For true wireless earphones, the Bluetooth chip is undoubtedly one of the most important components. The FW5 uses the high-quality Qualcomm QCC5141, which ensures stable and powerful Bluetooth audio transmission thanks to its dual-DSP and dual-core architecture. In addition, the FW5 is Snapdragon Sound-certified, which is a testament to its high-level audio capabilities.
Acoustic goodness - one ear at a time
The FW5 was developed by the same FiiO research team that created the wired high-fidelity flagship FH9. In the tiny space of a true wireless headphone, the team was able to fit a large 10mm dynamic driver responsible for the low and mid frequencies, while the higher frequencies are reproduced by two Knowles BA drivers. These drivers work together to produce powerful and textured bass while reproducing every detail in the treble.
More than just big - 10 mm dynamic driver
The FW5 features a large 10mm dynamic driver for the low and mid frequencies. The driver has been specially designed to maximise the sound quality of its N50 neodymium magnets. These N50 magnets, with their high magnetic density, allow for better dynamics and a larger soundstage for a thoroughly powerful sound.
Bringing out the big guns - DLC diaphragm with PU seal.
The FW5 uses PU as the material of choice for the gasket surrounding the dynamic driver's diaphragm, as its flexibility and high damping coefficient allow for richer vocals and faster transient response. The dynamic driver's diaphragm is made of DLC, which has beneficial properties such as high stiffness and low weight, resulting in less unwanted break-up of the dynamic driver. This results in less non-linear distortion and ultimately better resolution.
For every little detail - 2 high-frequency BA drivers per ear.
For high frequencies, 2 BA drivers are used for each channel. These BA drivers are placed in the sound tube near the ear to reduce high frequency loss as the sound waves travel to the listener's ear. This design ensures that even sounds at 16 kHz can still be heard clearly. Thanks to this design, the FW5 offers an airy, exceptionally detailed high-frequency response that captures every nuance of your music.
HiFi TWS is the new thing - support for the LHDC/aptX adaptive High-Res Bluetooth format.
With the FW5, FiiO underlines its claim to be at the forefront of new audio technologies. Not only is it Snapdragon Sound certified, it also supports LHDC/aptX Adaptive for the ultimate in true wireless audio quality. This support ensures both a massive upgrade in sending and receiving high-quality wireless audio, as well as a significant improvement in compatibility with various devices.
Carefully tuned sound - Pleasant frequency response curve
As the first TWS earphones developed entirely by FiiO, we didn't focus on features like active noise cancellation (ANC) with the FW5. Instead, we focused on providing the ultimate sound quality in a fully integrated TWS headphone. And while it's easy to adjust the frequency response curve via DSP, we chose not to. Instead, we chose to refine the physical design of the device to reduce distortion and retain the unique sound of the drivers - maximising sound quality through good design and fully respecting the original music.

Easy operation with 0 accidental touches - 4 physical buttons.
The development team chose a solution for operating the FW5 during use based on real-world testing and experience - 2 physical buttons for each ear unit. Physical buttons not only minimise microphonics during use, but the placement perpendicular to the wearing angle makes it easier to press the buttons without much effort.
A reassuring partner - 21+ hours of battery life.
Despite its powerful DAC chip, high-end Bluetooth chip and carefully designed audio circuitry, the FW5 has a battery life sufficient for everyday use. With its large built-in 60 mAh battery, the FW5 can operate for up to 6.5 hours on a single charge. The 380 mAh charger allows for a total battery life of more than 21 hours.
"Box" switch
When the FW5 charging case is opened, the earphones are automatically switched on and paired with the last device. When the earphones are placed back in the charging case, the FW5 earphones automatically turn off to save power.
* If the charging case is not powered, this function is not supported.
LED indicator lights
Both the charging case and the FW5 earphones have LED indicators to show you their status. The 4 indicator lights on the charging case show not only the remaining battery charge and charging status, but also whether the earphones are in the case. The earphones also have a white indicator light to show pairing and connection status.
Enjoy communicating - Dual-mic cVc noise cancellation
Each ear cup of the FW5 has 2 microphones which, together with cVc noise cancellation technology, provide clearer calls and make communicating a pleasure.
Multiple tastes in one place - 2 sets of ear tips included.
The FW5 comes standard with a set of symmetrical ear tips and 2 alternative sets of vocal ear tips for different sound preferences. The vocal earplugs are made of medical grade silicone with a soft texture that makes them comfortable to wear - a perfect combination of sound quality and high wearing comfort.
