FIIO OAK NANO HiFi IEM Earphones, 13.8mm Dynamic Driver,Titanium CNC,Interchangeable Sound Nozzles, 3.5mm/4.4mm/USB-C Plugs
The new OAK Series was inspired by classic wristwatch aesthetics. We celebrate the watchmaker's quest for the absolute, translating that dedication into rock-solid build quality and an elegance that never fades. Where sound meets light, individuality and sophistication take center stage.
OAK NANO is the first of the OAK Series, the spiritual successor to the FlIO FD7, and SNOWSKY's first flagship product. The OAKNANO was created through two years of research and development-a journey of unceasing refinement in pursuit of watch-grade craftsmanship and exceptional sonic character.
The engineering team chose beryllium metal for the diaphragm-the same precious material found in the FD7. Its rare combination of lightness and rigidity yields a distinctively clear and open sonic character. Together with a suite of sophisticated acoustic innovations, OAK NANO turns every listening session into a premium auditory indulgence.
Noble refinement Timeless elegance Pure titanium shell
The OAK NANO utilizes pure titanium-prized for its density and hardness-to create a body that remains pristine through the passage of time. Through a series of demanding and precision manufacturing processes-including mirror polishing, CNC machining, and PVD coating-its distinctive design language is brought to life, allowing the earphone's unique color, luster, and sharp contours to emerge with striking clarity.
Superior materials Sublime fidelity Beryllium alloy dome diaphragm
Inheriting the acoustic DNA of the legendary FllO FD7, theOAK NANO continues the legacy of beryllium-based diaphragms while charting a new path. Beryllium as a driver material is ultra-lightweight, exceptionally rigid, and superior to aluminum or titanium. Its low damping and high sonic velocity ensure zero unwanted coloration, making itthe premier choice for high-end audio.
While global supply chains have made pure beryllium increasingly rare, the OAK NANO utilizes a specialized beryllium alloy that mirrors the performance and sonic characteristics of the pure metal. We have pushed the boundaries of precision engineering to reduce the diaphragm's thickness, further unleashing the material's potential. This significantly enhances high-frequency extension,transient response, and distortion control, allowing for the precise restoration of micro-details-from the crisp strike of percussion to the delicate nuances present in vocals.
Reimagining the conductor：The next level of sonic purity-192° C liquid nitrogen cryo-treated silver-plated monocrystalline copper cable
We select 6N OCC (99.99998% pure) monocrystalline copper as our base material. This ultra-high purity conductor is inherently free of grain boundaries, offering exceptionally low resistance and high conductivity while eliminating oxygen and hydrogen impurities that degrade signal integrity.
To push electrical performance to the absolute limit,every conductor undergoes 100+ hours of deep cryo genic treatment. At -192° C, internal stresses within the metal are significantly released, thereby optimizing the microstructure. This internal restructuring facilitates a smoother and more natural transmission of audio signals.
High-flux magnetic control Unleashed dynamic power13.8mm external magnet dynamic driver
Building on the legacy of the FD7, OAK NANO stepsup to a larger 13.8mm driver unit with an enlarged and thickened magnet to match. A larger magnet means a stronger and more stable magnetic field.Lab testing confirms that magnetic flux density within the voice coil gap reaches nearly 1.5T, with distortion as low as 0.1% even at 114dB SPL. This immense magnetic force provides the raw driving power necessary for greater amplitude and minimal vibration distortion, resulting in superior transient response.
Custom-engineered,Excellence in every detail
Advanced dynamic driver design
Designed around the acoustic characteristics of a single dynamic driver, we spared no effort in refining OAK NANO's diaphragm, magnetic drive, and voice coil-eachdetail a deliberate step toward higher performance and a more fully realized sound.
Lighter, Stronger Beryllium Dome
In our pursuit of perfection, we've achieved the impossible:a larger berylium dome that is also significantly thinner.Paired with our newly engineered, high-flux magnetic circuit, the OAK NANO achieves lightning-fast transient response and breathtaking treble extension.
Dual sound signatures,Unlock a fresh sound anytime-Dual swappable tuning nozzles
The OAK NANO features swappable tuning nozzles,including both red and black acoustic filters to offer expanded tuning possibilities. Each tuning nozzle features differing densities of damping material to provide a total of two distinct sound profiles to match your personal listening preferences.
Seamless compatibility-Built around your needs-Detachable cable and swappable plugs
The OAK NANO is engineered for ultimate flexibility. With a fully detachable cable and a swappable plug system, it adapts effortlessly to any listening environment. Included are three interchangeable connectors to cover all your devices. Notable is the Type-C plug, which unlocks a rich suite of real-time tuning options-giving you the power of multiple setups in a single device.
