FiiO M21 | Digital Audio Player

The FiiO M21 Reinvents Entry-Level DAPs With a New Snapdragon 660 Processor and Desktop Mode, a First for FiiO in This Class Portable high-res lossless music player New octa-core 6nm Snapdragon 680 processor Features four Cirrus Logic CS43198 DAC chips Fully balanced 2-stage amplification 4.7-Inch compact HD screen Retro cassette-style case available A New Entry-Level Benchmark The FiiO M21 is equipped with the Qualcomm Snapdragon 680 processor. It has superior performance with less power consumption than the SoCs used by players in the same class. It provides a smooth user experience with the integration of Android 13. In addition, the 6nm process technology improves performance and lowers power consumption. Full of "Hearty" Power The four Cirrus Logic DAC chips allow for an eight-channel fully differential output design. This fully unleashes 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 purer sound with rich detail. Patented Desktop Mode Desktop Mode makes an appearance on an entry-level FiiO player for the first time in the M21. 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.  A Jump in Performance In portable mode, the M21 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 (300 ohms) peak drive voltage and 950mW (32 ohms) massive output power. This delivers desktop-level power output, making the player a better fit with a wider fit of earbuds or headphones for an auditory feast. Flagship-Grade Power There are separate power supply paths for 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. Hi-Fi 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. 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. 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. Global Audio Optimization FiiO developed a custom crystal oscillator specifically for the M21. It has been carefully selected to meet the 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. Long Battery Life and Fast Charging The M21's 4000mAh high-voltage battery provides up to 15 hours of ultra-long battery life. This effortlessly provides 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.
