*Data comes from the FIIO labs and is subject to variation in real-world usage. Actual results may vary depending on the environment and conditions.

Portable + Desktop ports
A new generation of crossover devices
In addition to the common outputs found on portable devices, it is uniquely equipped with a 6.35mm headphone jack, coaxial input and output ports, and an optical output port. This level of connectivity and compatibility goes well beyond what is typically found on portable devices, greatly enhancing its integration with desktop systems.

End-to-end lossless audio Pure enjoyment in any setting
Bluetooth 5.4, supports various codecs including aptX Lossless and LDAC.
Bluetooth 5.4, supports various codecs including aptX Lossless and LDAC.

Two ESS ES9039SPRO
8-channel flagship DACs
Extremely high dynamic range and ultra-low distortion ensure accurate reproduction of sound details, delivering rich and clear sound. The device features two dual-channel, ultra-low-noise ES9312 regulators working in conjunction with the two ES9039SPRO chips. This setup uses four independent power supplies, each dedicated to one of the four differential modules, resulting in enhanced dynamic range and ultra-low noise.

Five hardware gain levels Unrivalled 5000mW output power
With marked improvements in output power and voltage at every gain setting and impedance, the device delivers a superb sonic experience with all IEMs and over-ear headphones. Plug in a fast charger via the dedicated power port to engage the Ultra High Gain Mode, unleashing a massive 5000mW+5000mW of output power, allowing the M27 to easily handle even the most demanding dynamic musical passages.
HYPER DRIVE: FIIO’s proprietary super drive amp circuit, featuring ultra-large power reserves, ultra-low-impedance circuits, rapid copper block heat dissipation, and ultra- low-loss relay switching throughout the signal path.

Seamless battery protection through hardware and software
9200mAh safe high-voltage battery
Supports 35W fast charging via the QC3.0, QC4.0, PD2.0 and PD3.0 PPS fast charging protocols.
*Data comes from the FIIO labs and is subject to variation in real-world usage. Actual results may vary depending on the environment and conditions.

Removable battery pack
The battery can be removed and swapped, alleviating concerns about long-term battery degradation.
*The battery pack is not sold separately. If replacement is needed, please contact your local distributor.

Patented desktop mode
The battery is bypassed when used in this mode, allowing you to not worry about constant battery wear from high power output. This efficiently cuts down on the number of charge/ discharge cycles and thus prolongs battery lifespan.

6th generation proprietary
Digital Audio Purification System (DAPS)
New high-capacity FPGA + Dual RIVER femtosecond crystal oscillators
FIIO’s latest generation of its proprietary DAPS system introduces a newly developed high-capacity FPGA and dual high-performance femtosecond crystal oscillators. This combination delivers ultra-high precision and ultra-low jitter digital signal transmission, resulting in exceptionally pure and clear sound.

31-band high-precision lossless PEQ
AUTO EQ, for even greater convenience
This digital music player is the first to globally support a 31-band high-precision PEQ. Utilizing FIIO’s proprietary algorithms and interface, it allows for fine-tuned sound customization. This lets you simulate or correct a headphone’s frequency response curve to perfectly match your personal sonic taste.
Is manual fine-tuning too complex? AUTO EQ and sound presets make it easy to get started. AUTO EQ enables diverse sonic experiences—just upload or select your headphone's original data and your desired target curve. It also includes various built-in sound effects like Pop and Jazz, plus a specially tuned “FX17 Relaxed Sound” EQ designed just for the FX17 – giving it a richer, more enjoyable high-fidelity sound.

Desktop-class audio architecture Meticulously designed circuit
The six-stage fully differential audio circuit, built to full-size desktop standards, effectively displays audio dynamics, lowers crosstalk, and ensures signal stability and integrity to accurately render every last detail within the music.

Separate power supplies for digital and analog sections
Minimizes crosstalk between analog and digital sections for pinpoint digital accuracy and purer analog output, giving the audio performance a more robust foundation.

40W high-capacity reserve power conversion circuit
65A high-current, MOSFET low-loss managed power path
Massive energy storage capacitors

High-efficiency 3D cooling system
Highly efficient cooling inside and out Consistently cool high performance
A graphite vapor chamber and graphene thermal conduction pads are integrated into a seamless metal chassis. This design quickly and evenly transfers heat away, guaranteeing powerful, long-lasting performance.

Distributed copper heat sinks
The copper heatsinks effectively reduce the internal resistance rapidly transferring localized heat away. This ensures the headphone amplifier circuit operates consistently at peak performance.

Continuity and evolution A leading pioneer
The device maintains a bold, modern design while also being a pioneer in incorporating avant-garde aesthetics.
