M21 - Titanium Gold

Product Description

Re-modelling the Entry Level Benchmark

The M21 redefines the entry-level class with its flagship lineage. Its compact screen and class-defying performance are a massive step forward, Aiming to be a benchmark for an entirely new generation

Flagship SoC

The Qualcomm Snapdragon 680 has superior performance with less power consumption than the SoCs used by players in the same class. It provides a smooth experience with Android 13.

4xCS43198: Full of "hearty" power

The four DAC chips allow for an eight-channel fully differential output design, fully unleashing the potential of headphones with class-defying dynamic performance and high anti-interference capabilities. The headphone amplifier section adopts a two-stage circuit design: the first stage is responsible for voltage amplification, while the second stage handles current expansion - all ensuring pure sound with rich detail.

Patented Desktop Mode: Battery protection expert

Desktop mode makes an appearance on an entry-level FIIO player for the first time.
When desktop mode is enabled, the M21 is completely powered by an external power supply. The built-in battery is neither charged nor discharged, allowing you to use the player safely on the desktop without degrading its battery.

Portable/desktop dual power supply modes: A jump in performance

In portable mode, it operates with standard voltage power supply. When using the external power "Super high gain" mode, the player automatically switches to using a high-voltage power supply with 21Vpp (3000) peak drive voltage and 950mW (320) massive output power. This delivers desktop-level power output, making the player a better it with a wider range of earbuds of headphones for a truly extraordinary auditory feast.

Go back to the Walkman era with just one touch

The custom cassette-style protective case paired with an exclusive retro Ul and tailored vintage sound effects all take you on a nostalgic journey back to the Walkman era... Remove the protective case to seamlessly switch back to the original system, giving you the flexibility to use it how you want to.

Please note this Cassette Case will be available for separate purchase and is not-included with the M21. A regular Clear Protective case is included.

True quality: Inside and out

The fully aluminum alloy body with an AG frosted glass back offers a delicate texture and comfortable grip. The screen features an oleophobic coating that significantly reduces fingerprints and smudges, making for smoother touch operation.

Digital and analog partition shielding: Purely heavenly sound

The digital and headphone amplifier sections exist in separate partitions and each is equipped with independent shielding covers for isolation. This not only further reduces signal crosstalk but also enables efficient heat dissipation, delivering purer sound.

Flagship-grade power

There are separate power supply paths for the digital and analog circuits, which effectively reduce crosstalk between the two. The result is more precise digital processing, purer analog output, and enhanced driving power. The analog circuit is further subdivided into multiple independent power supplies for components such as the DAC and headphone amplifier. This clean and robust power delivery enhances the dynamic range and leads to greater reproduction of details in the audio - for a more refined and natural sound.

High-end HiFi Parts For better sound

In the M21's audio circuit are high-precision thin-film resistors and low- temperature-drift capacitors that ensure refined and stable sound quality - specifically the greater consistency between the left and right channels and across all frequency ranges. Additionally, fine circuits such as the DAC and headphone amplifier are equipped with over 10 low-impedance, high-capacity tantalum capacitors. These provide abundant energy reserves and a robust power supply for more powerful, dynamic sound.

Global audio optimization: 5th-gen FPGA + dual custom femtosecond crystal oscillators

FIIO developed a custom crystal oscillator specifically for the M21, which has been carefully selected to meet femtosecond-level standards, in order to ensure consistency and stability in its output. With a high-precision, low-jitter unified clock source, it accurately matches PCM and DSD audio at various sampling rates, ensuring precise reproduction of digital audio signals.

15h long battery life Exploring the world of music

The M21's 4000mAh high-voltage battery provides up to 15 hours of ultra-long battery life, effortlessly providing the energy for extended listening sessions when commuting or traveling, allowing you to fully immerse yourself in the world of music. It also supports 20W PD fast charging, enabling quick recharges even during short breaks.
