FiiO S15 black
FiiO S15 black
Thanks to its powerful Android-based software and flagship AKM upsampling/DAC combination, the FiiO S15 mini system offers a smooth and detailed music experience from both integrated apps and its own FiiO Music interface. Control via the 7.84" S15 touchscreen or the companion app includes multiple operating modes. The Pure Music and USB DAC functions allow you to disable unnecessary processes for optimal performance. HDMI ARC, along with an additional HDMI input, makes it easy to integrate into a home cinema setup, while a wide range of digital and analogue outputs allows for easy integration of the S15 into a hi-fi system. The first fully-fledged all-in-one media streamer, the FiiO S15, excels in media streaming, network streaming, LAN playback, local playback, decoding, pre-amplification and as a digital jukebox. It is equipped with top-of-the-line components, a wide range of interfaces and numerous control options, while being fully compatible with external DACs, amplifiers and speakers.

A modern streamer designed for a premium listening experience
With its uncompromising high performance and wealth of easy-to-use music control features, it redefines what a modern media streamer can do. The S15 has a standard width of 43cm, making it easy to match with other equipment in the living room to create a unified audio system. Its 5kg all-metal body and stable anti-slip feet effectively reduce sound degradation caused by vibrations.
Clear interface with Android 12
Featuring a larger colour display than similar products and a custom version of Android 12 with a special landscape display system, the picture is clear and easy to read. Operating the device is intuitive, so you can comfortably use its various functions right out of the box. Every touch gets you exactly where you need to go, quickly and easily. The S15 uses a high-quality, low-noise custom-designed transformer to ensure a clean power supply. The device is also equipped with four 4700µF ELNA audio capacitors, which provide a sufficient power reserve for stable and continuous operation.
Ultra-low noise and reference digital synchronisation
A pair of high-performance ACCUSILICON femtosecond oscillators with ultra-low noise. For the first time, FiiO uses two top-of-the-line ACCUSILICON AS318-B series femtosecond oscillators with ultra-low phase noise (45.1584MHz and 49.1520MHz), which have undergone a meticulous selection process. They effectively reduce the influence of phase noise on the audio signal, resulting in high-precision decoding and digital output. When paired with high-quality external DACs and amplifiers, reference-level sound can be achieved.
Flagship AKM DAC for reference-quality sound
Just like the Q15, K9 AKM and M23 models, the S15 uses the acclaimed flagship AKM AK4191 + AK4499EX DAC combination. The setup is based on a new design that completely separates the digital and analogue sections and uses “DWA ROUTING” technology. The result is a higher signal-to-noise ratio and lower noise across different volume levels. Your listening experience will have a cleaner background, better resolution and a natural, effortlessly relaxed sound.
Fully balanced audio design for pure sound
The S15 uses a fully balanced design from the DAC section to the preamplifier. This solution significantly reduces noise and crosstalk, improving the quality of both the line and preamp outputs, with a choice of fixed or variable gain. The IV, LPF, and other audio sections use precise, low-noise OPA1612 op-amps with a high supply voltage to reproduce music dynamics as faithfully as possible.
Physically separate audio sections with no interference
The digital, analogue, and power supply sections are physically separated to prevent mutual interference. This ensures signals are processed accurately and all the dynamics of the music are preserved. The result is an exceptionally pure and natural sound performance. With FiiO's custom PEQ algorithm and interface, you can finely adjust frequency points, gain, bandwidth, and Q value. You can also correct the frequency response of your headphones or simulate the character of other models to suit your preferences.
Precise, low-noise power supply architecture
The design effectively prevents crosstalk between the analogue and digital audio circuits. It also provides better power isolation and greater resistance to interference. The analogue section uses a multi-stage power supply with precisely separated sections for components such as the DAC and LPF circuits. Each stage uses a series of precision low-dropout regulators (LDOs) for secondary regulation to ensure a stable, consistent, and clean power supply.
Modern horizontal FiiO OS interface
FiiO's new landscape display interface is specially optimised for widescreen displays like the one on the S15. It not only offers a clean and intuitive layout but also enhanced visual effects for an even more impressive experience. You can control it via touch, the mobile app, or a Bluetooth remote, whichever suits you best. A special version of the FiiO Music app, tailored to the S15 display, provides quick access to various music playback and setting functions. It also supports visual audio effects, such as VU meters, for a more engaging visual experience. Unlike other streamers, the S15 offers extensive customisation options. You can freely adjust the home screen layout to your own needs.
Smart control directly from your phone
FiiO places great emphasis on providing the best possible user experience. That's why a dual-screen function has been designed in the companion app, which allows you to conveniently and comprehensively control the S15 directly from your phone. The S15 supports HDMI 2.0 decoding, HDMI output, and HDMI ARC (Audio Return Channel), making it an important part of your audiovisual system. Using the included Bluetooth remote control, you can instantly immerse yourself in a first-class audiovisual experience. The HDMI decoding/output supports sampling up to 192kHz/24bit.
