FiiO has unveiled the M21, a portable digital audio player (DAP) that redefines the entry-level Android-based DAP market with its impressive specifications, sleek design, and accessible price point of £279 / $329 / €329. Following the success of the award-winning JM21, the M21 combines flagship-level hardware, intuitive retro aesthetics, and robust performance, making high-resolution audio more attainable for discerning music enthusiasts.
Flagship Performance in a Compact Package
The FiiO M21 is powered by an octa-core Qualcomm Snapdragon 680 chipset running Android 13, ensuring smooth and responsive performance for both native and streaming applications. Its compact 4.7-inch HD IPS touchscreen offers a user-friendly interface, while 4 GB of RAM and 64 GB of internal storage (52 GB usable) provide ample space for music libraries. With microSD support expandable up to 2 TB, the M21 is ready to house even the most extensive collections of high-resolution audio files.
The M21 supports high-resolution PCM files up to 32-bit/768kHz, DSD512, and full MQA decoding, alongside Bluetooth codecs including LDAC, aptX HD, and SBC, making it a versatile choice for both wired and wireless listening. Its aluminum alloy body with an AG-frosted glass back not only exudes premium build quality but also ensures durability and a comfortable grip.
Quad DAC Architecture for Superior Sound
At the core of the M21’s audio prowess are four Cirrus Logic CS43198 DAC chips arranged in a matrix configuration, designed to minimize crosstalk and noise for a clean and dynamic soundstage. Paired with a two-stage amplification circuit—handling voltage and current gain separately—the M21 delivers exceptional audio clarity and power, capable of driving a wide range of headphones with ease.
The M21’s audio circuit is further enhanced by high-precision thin-film resistors, low-temperature-drift capacitors, and over 10 low-impedance tantalum capacitors, ensuring consistent and refined sound across all frequencies. A custom femtosecond crystal oscillator and FiiO’s 5th-generation FPGA architecture provide precise timing for PCM and DSD formats, guaranteeing faithful audio reproduction.
Innovative Desktop Mode for Versatile Use
A standout feature of the M21 is its patented “Desktop Mode,” a first for FiiO’s entry-level Android players. When connected to an external power supply via a secondary USB-C port, the M21 bypasses its internal battery, delivering up to 21 Vpp peak voltage and 950 mW per channel into 32Ω loads—performance levels comparable to high-end desktop DAC/amplifiers. This mode not only protects the 4000 mAh battery from degradation but also allows the M21 to serve as a high-quality streaming component in a hi-fi system.
In portable mode, the M21 offers robust battery life, providing up to 15 hours of playback via the 3.5 mm single-ended output and 11.5 hours via the 4.4 mm balanced output. With 20W PD fast charging, the player is quickly ready for extended listening sessions. The updated FiiO Control app, available for smartphones, offers full control over settings, including advanced parametric EQ filters for personalized sound tuning.
Retro Aesthetics with Modern Flair
Adding a touch of nostalgia, FiiO offers an optional retro cassette-tape-style protective case (sold separately) that transforms the M21’s appearance into a nod to the Walkman era. Complete with a vintage UI and tactile buttons, this case connects via three metal contact points for seamless functionality, blending old-school charm with cutting-edge technology. A standard clear protective case is included with the M21 for those preferring a minimalist look.
A New Standard for Entry-Level DAPs
Priced at £279 / $329 / €329, the FiiO M21 sets a new benchmark for affordable high-resolution audio players, offering flagship-grade performance in a portable, user-friendly package. Its combination of quad DAC architecture, powerful amplification, innovative Desktop Mode, and retro-inspired design makes it an attractive option for audiophiles and casual listeners alike.
The FiiO M21 is available now, and its arrival has already generated excitement among audio enthusiasts, with early feedback praising its sound quality, versatility, and value. For those seeking a DAP that delivers premium audio without breaking the bank, the M21 is poised to become a standout choice in 2025.
