Portable Desktop-Class Music Player
FiiO - M17
Redefining portable expectationsThe FiiO M17 smart desktop-class music player is a completely new chapter for FiiO digital audio players. Its desktop-grade DAC, amplification, power supply, and other components give it the output power and sound quality to rival and perhaps even surpass highly-regarded desktop systems, but in a portable package. The M17 truly redefines what is possible with portable audio players.
The left and right audio channels each contain a desktop-class, 8-channel ES9038PRO flagship DAC. Meaning that each audio channel has 8 parallel outputs summed together for superior resolution and minimal distortion for extremely pure audio reproduction. Desktop-class amplification also plays an important role in the M17. FiiO and THX worked together to develop the exclusive THX AAA 788+, an upgraded version of the original op-amp. Compared to the original, output power is increased by 225% up to 3000mW per channel with a lower output impedance, allowing it to power all kinds of headphones seamlessly.

Desktop-Grade Components
more power, more connectivityWhen using battery power, there are 4 gain levels: low, medium, high, and headphone mode. When using DC mode, the enhanced over-ear headphone mode gain is enabled, providing a truly desktop level of amplification gain. In balanced output, gain can get as high as 16dB allowing the M17 to easily drive most headphones. Thanks to its larger size, the M17 features multiple connectivity options allowing for many different convenient uses.
The M17 also features two power supplies, a battery power supply, and a power supply powered by external DC power. The battery power supply allows you to use the M17 in situations where there is no access to a power outlet. Under DC power supply, voltage in the analogue circuit is increased by 35% up to 11.5V compared to under battery power supply; and the battery is kept healthy as it isn't used in this mode.
With exceptional audio quality comes large power consumption, so effective heat dissipation was a main priority when designing the M17. Not only are "H" type heat dissipation and VC liquid cooling technologies adopted, the M17's 151g unibody aluminum alloy frame also effectively transfers heat out of the device. The cooling fan stand also further makes sure heat is rapidly transported away.
Desktop-Caliber Internals
High-end TI OPA2211 op-ampA voltage noise as low as 1.1nV@1KHz and THD+N of -136dB results in extremely clean amplification.
470mF DMF supercapacitorEquivalent to 10,000 47uF tantalum capacitors and with very low ESR of 45mΩ (only 15% of that of tantalum capacitors), providing a solid foundation for a large power supply.
Ultra-low noise LT3045 LDOAn ultra-low noise, ultra-high PSRR low-dropout voltage linear regulator featuring Linear Technology's LDO architecture an extremely low RMS noise of 0.8uVRMS in the 10Hz-100kHz frequency band for stable, clean power to the DAC chip.
NDK femtosecond crystal oscillatorProvides a high-precision, low-jitter unified clock source for the whole audio circuit.
A True Smartphone-Like Experience
Qualcomm Snapdragon 660Equips the open Android 10 that allows installations of third-party apps (no SRC limit at all).
Flagship QCC5124 chipBluetooth 5.0 with support for aptX Adaptive. Bluetooth reception: SBC, AAC, aptX, aptX-LL, aptX-HD, aptX Adaptive, LDAC、LHDC. Bluetooth transmission: SBC, AAC, aptX, aptX-HD, LDAC.
XMOS receiver chipUltra-low latency, supports up to DSD512 and 32-bit/768kHz.
Gravity sensorScreen can be automatically rotated like a smartphone thanks to the gyroscope.
Extremely fast transferWith USB 3.0 writing speeds can hit up to 100M/s, allowing file transfers to complete within minutes or even seconds.
MQA SupportedSupports MQA unforlding for laster-level sound.
10-Band PEQ Precise Tuning
made for great soundThe PEQ (Parametric Equalizer) function was designed for the M17, which supports 10-band self-defined tuning.
On the FiiO Music App in the M17, users can self-adjust the frequency, gain level, Q value, etc., achieving more accurate frequency response among every frequency range while ensuring high-fidelity sound quality. It supports up to 192kHz/24bit under PEQ style.
Physical Digital-Analogue Separation
reduced interferenceBuilt-in the M17 are 17 PCBs with immersion gold finish, with the analogue and digital sections physically separated by being on two different boards to reduce interference between the two portions.
7 high-conductivity copper alloy shields also provide shielding to greatly reduce internal and external electromagnetic interference on analogue audio signals within the M17.
Highly-Optimized Modular Internal Structure
years of exepertiseThe M17's design took 1.5 years to complete, going through 6 major design iterations with 12 rounds of internal structural design optimization. The result is a device that makes excellent use of its internal space.
Within the M17 are carefully stacked analog and digital boards with thoughtful use of stainless-steel hexagons - which allowed FiiO to add nearly twice the surface area of PCBs compared to normal in such a limited space.
World-Class User Experience
7th-gen mech designThe futuristic, seamless, CNC-finished aluminum unibody design evokes a sense of technological wonder. The mech-inspired sharp lines of the body, buttons, and atmospheric lights give the M17 a bold and charismatic aura.
Press or twist to enjoyThe volume can be adjusted either using an analogue potentiometer knob or using buttons. Quickly and easily go through 120 levels of volume through either method.
Bigger screen for a brighter sheenA larger screen allows you to more easily enjoy stunning visuals. Feast your eyes upon an upgraded 5.99 inch, 1080*2160 FHD+ 18:9 high-definition incell display.
9200mAh batteryThe huge 9200mAh battery allows for a battery life up to 10 hours on the M17. It can be charged either through USB or through DC in from an external AC adapter.
