The FiiO FF5 and FF3 have proven themselves to be well-received members of the FF family, with their precise positioning and their unique yet well-executed design winning over the hearts of many.
We wanted to allow even more listeners to experience the sound quality of the FiiO FF series. Thus, being careful to retain the unique design and qualities of the previous FF earbuds in an optimized affordable package, we bring you the newest and most junior member of the FF family – the FiiO FF1.
Extra-large driver in its class, grand sound
Large 14.2mm dynamic driver
The FF1 features a large 14.2mm dynamic driver, not common in its nominal class. This driver not only democratizes high-end driver materials to be more affordable, it also introduces a new acoustic design. This driver is part of the second generation of dynamic drivers of FiiO FF series. Thanks to its scientifically-informed design, the resonance frequency of the FF1 driver helps to acquire more extended, dynamic and textured bass for an overall grander sound.
The driver and its diaphragm are the core of an earbud, being where sound is generated. In order to provide sound quality beyond its nominal class, we democratized high-end driver materials to be accessible at an affordable price. Not only is the FF1’s driver highly rigid and lightweight with sufficient damping, but a special suspension system for the gasket was specifically designed for the FF1 to allow the driver to move better. This results in better quality and robust bass, sweet mids and vocals, for a sound that simply oozes atmosphere.
 Beryllium-plated diaphragm is highly rigid yet lightweight, leading to reduce unwanted breakup of the driver and thus less distortion. Measured distortion: ＜0.2%@94dB (150~20kHz). The driver is also highly responsive, for excellent transient performance.
 The above test data is from FiiO Audio Labs.
Experience high-quality bass
When the FF1 is worn openly, the effective frequency response reaches down to an astonishing 38Hz, better immersing the listener into their music. For better bass performance, it is recommended to use the earbuds with sponge covers.
Open wearing refers to normal wearing of the earbud with sound leakage and without sponge cover.
The effect frequency response range is 10dB quieter than the sound level of the lowest resonance frequency.
The above test data is from FiiO Audio Labs.

A subtle gesture, making you happy
Open sound and comfortable to wear
For earbud users, comfort is the top priority. For even greater comfort, based on the large amounts of user feedback of the FF series we optimized the diameter of the earbud shells that make contact with the ear, reducing it from 16.5mm to 16.2mm. While a subtle move, it is one that displays our commitment to listeners.
Almost invisible to wear Lightweight 3.2g
As an affordable entry-level earbud, the FF1 is more likely to be used in a wide range of scenarios and for longer – thus we needed to ensure the earbuds are comfortable for long listening sessions. The FF1 of a single earbud is only 3.2g, making it almost invisible in your ears for excellent comfort when wearing it for long periods of time.
In the dead of night, singing a solo for you
Non-intrusive when lying on your side
The development team’s goal for the FF1 was to make it a true multi-purpose“all-arounder”, to be the ideal all-day HiFi companion. Without compromising on sound quality, the acoustic engineers carefully minimized the volume of the earbuds such that they do not protrude from the ears when worn, letting you comfortably use them even while sleeping or lying on your side. Whether you are watching dramas, gaming, or listening to music on your side at night, the FF1 is there for you every starry night.
Sports or leisure, HiFi is always with you
Included anti-slip silicone rings, silicone wing hooks
Included with the FF1 are 3 pairs of different sizes of anti-slip silicone rings, allowing the earbuds to comfortably stay in your ear no matter your ear size. In addition, thanks to the open-wearing nature of the FF1, using the earbuds is relatively suitable and okay for activities such as hiking or biking. Thus, also included with the FF1 are a pair of silicone wing hooks, truly letting you experience HiFi even when working out!
 Open wearing refers to normal wearing of the earbud with sound leakage and without sponge cover.
With one button, communicate with the world
Microphone with in-line controls
Looks can be important
Two colors available
The FF1 is available in obsidian black and racing silver, two stylish colors for you to choose from.
0.78mm 2-pin detachable cable
The FiiO FF1 features a 0.78mm 2-pin connector detachable cable, paving the way for future upgrades to your listening experience.
Care shows in details. The FiiO team compacts the bulky 0.78mm 2 pin connector in a tiny oval shape, which achieves non-intrusive feelings when lying on your side. In addition, the left earbud connector also has a handy tactile indicator that allows you to easily distinguish between the left and right channels of the cable.
*Note: The FF1 will be compatible with the FiiO-designed headphone cable, which is still under development.
Great sound, custom-made for you
2 different sponge covers included
With 2 different kinds of sponge covers included, tune the FF1’s sound to your exact liking.
Open hole: transparent sponge cover, robust bass, clear treble No hole: transparent sponge cover, robust bass, lush vocals
Sound comes from the movement of air, and how to harness that movement of air is what acoustic engineers focus on. For the FF1, the acoustic engineers designed a slender acoustic resistance pipe that starts from the top of the FF1 ear stem going to its rear. This concealed acoustic pipe not only contributes to the FF1’s elegant design, but also allows the air inside the earbuds to flow smoothly. Most importantly, the acoustic resistance pipe can resonance frequency of the earbud’s body and reduce bass loss, giving you deeper yet purer high-quality bass.
