The mature evolution of R2R from desktop to portable

FIIO's self-developed R2R resistor array,
completely ports the desktop architecture to a portable player for the first time.

FIIO's self-developed R2R resistor array

From desktop to portable, the mature development of R2R


FIIO's self-developed R2R resistor series completely ports the desktop architecture to a portable player for the first time. After auditioning by several experienced acoustic engineers and gathering feedback from users at global exhibitions, we finally bring you:

The mellow analog charm emphasized by R2R and the balanced characteristics of high-level audio sources.

Ultra-large storage combination

Ultra-large storage combination, long-lasting and smooth experience


The ultra-large storage combination of Qualcomm Snapdragon 680 with 8GB RAM + 128GB ROM is a level-jumping existence in its class. Streaming media playback and multi-tasking switching are easy and smooth. Ample performance and space calmly cope with future functional expansions, ensuring stability and durability for long-term use.

USB DAC Audio and Video Synchronization

USB DAC Audio and Video Synchronization, Achieved by a Dedicated "Core"


High latency in USB DAC compromising your cross-device music and video experience?
With the support of the independent XMOS XU316 chip, the performance is powerful and the latency is extremely low, ensuring a consistent audio and video experience in all scenarios.

768kHz-32bit/DSD512
5.5-inch high-definition large screen

5.5-inch high-definition large screen, more than just big


Large screen experience, instant immersion, excellent audio and video experience. Brand new paper, pixel, and VU meter themes make every song full of immersion and a sense of ritual.

Thin and handy

Thin, lightweight, and perfectly fits your hand


The minimalist design of the FIIO M21 expands with clean and premium lines on the sides. The exquisite design cleverly achieves a delicate balance between size and hand feel.

Thin and handy, not just in parameters, but giving a perfect fit every time you hold it.

Flagship co-developed DAPS audio purification system

Flagship co-developed DAPS audio purification system
High-capacity FPGA + Dual custom femtosecond crystal oscillators


The same clock management system as the flagship M27 brings a qualitative leap in digital audio processing efficiency and initial quality compared to the M23.

Auto EQ

Supports Auto EQ
Ideal listening experience, one-click modulation


10-band lossless PEQ manual adjustment too complex? AUTO EQ automatically matches your earphones, matching the ideal listening experience with one click, delivering precise and lossless sound quality. The APP also has built-in sound effects such as Pop, Jazz, and Classical, which can be further customized and adjusted band by band, allowing you to modulate your ideal sound.

Achieves precise volume control

Brings low noise and achieves precise volume control


The pre-amp uses TI op-amps for I/V conversion and signal conditioning, bringing a wide and natural soundstage performance;

The post-amp continues to use four INA1620 headphone amplifier chips, with a parallel output of up to 1100mW+1100mW, easily driving various headphones;

Coupled with independent electronic volume control, it balances both dynamics and details.

High-end Components

High-end Components

  • Brings low noise and achieves precise volume control
Level-jumping large dynamic performance, retracting and releasing freely

  • 8 Rubycon film capacitors
Natural and transparent mid-frequency, soft and smooth high-frequency

  • 4 Ti Burr-Brown wafer-level precision integrated INA1620
Significantly reduces crosstalk, and remains unaffected by inter-channel response even when overdriven or overloaded

  • Utilizes fully differential volume control chip NJW1195A
Brings low noise and achieves precise volume control

Refined Power Supply System

Refined Power Supply System


Digital and analog independent power supply. The analog section also adopts 3 independent power supply systems for R2R, pre-amp, and headphone amp, bringing a more delicate and natural sound quality performance.


The headphone amp power supply is equipped with 2-level voltage switching. The over-ear mode will activate high-voltage power supply, increasing the output power to 1100mW+1100mW, better driving various earbuds or over-ear headphones.

Partitioned Layout Enhancement

Partitioned Layout Enhancement, Restoring True Sound


The digital core module, R2R DAC module, headphone amplifier module, and power supply module are distributed in partitions and equipped with independent shielding covers for isolation, further reducing signal crosstalk, resulting in a darker music background, a cleaner soundstage, and richer details.

15.5 hours ultra-long battery life

15.5 hours of ultra-long battery life, relieving power anxiety


Featuring a selected 4400mAh high-capacity battery, the battery life for both single-ended and balanced outputs has been significantly improved compared to the M23. It also adopts low-voltage fast charging, which charges quickly without getting hot. With ultra-long playtime and fast recharging, it easily accompanies you through every music moment.

*Data is from the FIIO Lab. Actual results may vary depending on test environments and conditions. Please refer to actual usage.

Partitioned Layout Enhancement

Dual Type-C ports, dual purposes


Over-ear mode is equipped with four gain levels: low, medium, high, and over-ear mode. Plugging a fast charger into any Type-C port can activate the over-ear mode, further unlocking the gain and driving power. The output power reaches up to 1100mW+1100mW per channel, which can better drive high-impedance over-ear headphones.

Patented Desktop Mode
Bypasses the battery entirely, so you don't need to worry about power consumption from high-power output; effectively reduces the number of battery charge and discharge cycles, prolonging battery life. Patent number: ZL202321946664.8
