The FW5 integrates FiiO’s various cutting-edge technologies to bring a fully integrated, high-fidelity true wireless solution. This is among the first TWS earphones to integrate a high-end Bluetooth chip, high-performance DAC, and a meticulously designed audio circuit to achieve a big quality jump in all aspects. Let the FWS show you what new high-fidelity TWS earphones are truly capable of.
Independent AK4332 DAC
Let there be high fidelity in a true wireless earphone! The FW5 contains an efficient AKM VELVET SOUND DAC – the AK4332 which features high-performance decoding abilities. This chip is capable of signal-to-noise ratio up to 106dB, distortion as low as 0.0016%, and dynamic range up to 102dB.
Qualcomm QCC5141 Bluetooth chip
For true wireless earphones, the Bluetooth chip is undoubtedly one of the most important parts. The FW5 employs the high-end Qualcomm QCC5141 for stable and high-performance Bluetooth audio thanks to the chip’s dual DSP and dual-core architecture. Additionally, the FW5 is Snapdragon Sound certified as a testament to its highly capable audio abilities.
One ear at a time
The FW5 has been developed by the same FiiO R&D team that created the high-fidelity wired FH9 flagship. In the tiny space of a true wireless earphone, the team managed to fit a large 10mm dynamic driver that handles the low and mid-range frequencies, while higher frequencies are reproduced by 2 Knowles BA drivers. These drivers work together to give powerful yet textured bass while reproducing every last detail in the treble.
More than just big
10mm large dynamic driver
The FW5 features a large 10mm dynamic driver for the low and mid frequencies. The driver has been designed specifically to maximise the sound quality from its N50 neodymium magnets. These N50 magnets, with their high magnetic density, allow for better dynamics and make the sound stage more grand for a thoroughly bold sound.
Bringing out the big guns
DLC diaphragm with PU gasket
The FW5 uses PU as the material of choice for the gasket surrounding the diaphragm of the dynamic driver, since its flexibility and high damping coefficient allow for lusher vocals and faster transient response. The diaphragm of the dynamic driver is made of DLC, which features favourable properties such as high rigidity and lightweight which allow for less unwanted breakup over the dynamic driver. This leads to reduced non-linear distortion and ultimately better resolution.
For every last 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 sound waves travel to the listener’s ear. This design ensures that even tones like those at 16kHz still come through clearly. This design allows the FW5 to feature an airy, exceptionally detailed treble that captures every nuance of your music.
HiFi TWS is the new thing
High-Res LHDC/aptX Adaptive Bluetooth format support
The FW5 reaffirms FiiO’s commitment to being at the forefront of new audio technologies, with not only Snapdragon Sound certification but also support for LHDC/aptX Adaptive for the ultimate quality in true wireless audio. This support ensures both a massive upgrade in the sending and receiving of high-quality wireless audio and a major improvement in compatibility with various devices.
Pleasing frequency response curve
As the first TWS earphones fully developed by FiiO, for the FW5 we did not put our focus on features such as active noise cancelling (ANC). Instead, we focused on bringing the ultimate in sound quality in a fully integrated TWS earphone. And while it is easy to adjust the frequency response curve via DSP, we chose not to do so. We instead chose to refine the physical design of the unit to reduce distortion, retain the unique sound of the drivers – to maximize the sound quality through good design to fully respect the original music.
Easy to use with 0 accidental touches
4 physical buttons
The development team chose a solution for operating the FW5 during usage based on real-life testing and experience – 2 physical buttons for each ear unit. Physical buttons not only minimise microphonics during operation, but placing them perpendicularly to the wearing angle also makes the buttons easier to press without resorting to too much force.
A reassuring partner
21+ hours battery life
Despite packing a high-performance DAC chip, high-end Bluetooth chip, and a carefully designed audio circuit, the FW5 features battery long enough to easily meet daily usage needs. With its large built-in 60mAh battery, the FW5 can be used for up to 6.5 hours on a single charge. The 380mAh charging case allows for total battery life of more than 21 hours.
Power switch linked to the case
When opening the FW5 charging case, the ear units are automatically turned on and paired with the last device. When the ear units are placed back into the charging case, the FW5 ear units automatically turn off to save power.
* When the charging case is out of power, this functionality is not supported
LED indicator lights
Both the charging case and the FW5 ear units each feature LED indicator lights to let you quickly know their status. The 4 indicator lights on the charging case not only indicate the battery remaining and the charging status, but also indicate if the ear units are in the case. The ear units each also contain a white indicator light that clearly indicates pairing and connection status.
Dual-mic cVc noise cancellation
Each ear unit of the FW5 features 2 microphones that work together with cVc noise cancellation technology for clearer voice calls to make communicating a joy.
Multiple flavours in one place
2 sets of ear tips included
The FW5 comes standard with a set of balanced ear tips as well as 2 alternate sets of vocal ear tips for different sound preferences. The vocal ear tips are made with medical-grade silicone featuring a soft texture that makes it comfortable to wear – making them a perfect combination of sound quality and superior comfort.
