M21 reshapes the entry-level standard with flagship genes, and its interior and exterior designs are full of "core" significance and sincerity. The handy compact screen and class-defying performance are comprehensively upgraded, dedicated to creating a new generation of strength paradigms.
Flagship SoC
New Entry-Level Benchmark
A brand-new processor that leaps beyond products of the same class — Qualcomm Snapdragon 680. Its performance strength defies its class, with more excellent power consumption performance. Paired with Android 13, it runs silky smooth.
The 4-group, 8-channel fully differential output design fully unleashes its potential, possessing class-defying large dynamic performance and high anti-interference ability. The headphone amplifier section adopts a front-and-rear 2-stage circuit design: the front stage handles voltage amplification, while the rear stage handles current expansion, ensuring pure sound quality and rich details.
Consists of two Cirrus Logic flagship DACs CS43198 paired with two high-performance op-amps SGM8262 to form a fully balanced audio architecture. Evolved through multiple products, it further optimizes hierarchical power supply and front/rear stage gains, presenting wider dynamics and a more moist musical sense.
FIIO's entry-level player features Desktop Mode for the first time. When Desktop Mode is activated, the M21 is completely powered externally. The built-in battery is neither charged nor discharged, allowing it to be used as a desktop device, effectively prolonging the battery's lifespan.
Patent Number: ZL202321946664.8
Specially developed custom cassette-style protective case, linked with a dedicated retro UI, and paired with specially tuned retro sound effects, dreaming back to the Walkman era... Remove the protective case to seamlessly switch back to the original system for smarter and more free control.
*The cassette-style protective case is optional or sold separately.
*When the cassette protective case is installed, touchscreen operation is not supported; only button operation is supported.
All-aluminum alloy body and AG frosted glass back cover provide a delicate touch and a comfortable grip. The screen comes with an oleophobic coating, which effectively reduces fingerprints and smudges, making touch control even smoother.
The digital module and headphone amplifier module are partitioned and isolated with independent shielding covers. This not only further reduces signal crosstalk but also achieves highly efficient heat dissipation, bringing a purer sound quality experience.
Digital and analog split power supply effectively reduces crosstalk between digital and analog circuits. The digital is more precise, the analog is purer, and the drive is more abundant. In addition, the analog circuit further subdivides into multiple independent power supplies for the DAC and headphone amplifier. The pure and powerful power supply improves the dynamic range and detail performance of audio signals, making the sound more delicate and natural.
The audio circuit of the M21 uses high-precision film resistors and low temperature drift capacitors, ensuring delicate and stable sound quality performance, with higher consistency across left and right channels and various frequency bands. Furthermore, the refined circuits such as the DAC and headphone amplifier are distributed with over 10 low-resistance, high-capacity tantalum capacitors. The power supply is robust, storing abundant energy for a more surging sound.
FIIO has custom-developed miniaturized active crystal oscillators specifically for the M21, screening them at the femtosecond level to ensure consistent stability of the output. The high-precision, low-jitter unified clock source accurately matches PCM and DSD audio at various sample rates, ensuring precise restoration of digital audio signals during transmission.
Featuring a 4000mAh high-voltage battery, the ultra-long battery life of up to 15 hours easily meets the needs of commuting, traveling, or long-time listening, allowing you to fully immerse yourself in the music world. It also supports 20W PD fast charging, enabling rapid recharging during brief breaks.
