Fiio M21 Portable Hi-Res Music Player - Blue

.

The FiiO M21 is a high-resolution portable music player designed to deliver desktop-level audio performance in a compact form factor. Thanks to the powerful 6nm Snapdragon 680 8-core processor and Android 13 operating system, it guarantees speed, fluidity, and full compatibility with all lossless streaming apps like Tidal, Qobuz, Apple Music, and many more.

.

For uncompromising sound quality, it integrates four CS43198 DACs with a fully balanced dual-stage amplification architecture, capable of delivering detailed, dynamic, and natural sound. Output power reaches up to 950mW, ideal even for high-impedance headphones.

.

The design includes dual USB-C ports, low-jitter coaxial output, and balanced 4.4mm and unbalanced 3.5mm audio outputs, which can also be used as line out. The 4.7-inch HD display ensures a clear and responsive interface, while dual power support (portable and desktop) makes the M21 perfect for both mobile and desktop use. Completing the package is a refined, retro-cassette-style protective case, combining vintage aesthetics with protection.

.

Smooth performance with low power consumption

The FiiO M21 is powered by the Qualcomm Snapdragon 680, a 6nm octa-core SoC that delivers superior performance and lower power consumption than chips used in other players in the same price range. Combined with Android 13, it ensures a smooth, fast user experience, and is highly compatible with leading Hi-Res audio apps.

.

Balanced Power and Precision

The inclusion of four CS43198 DACs enables a fully differential eight-channel configuration, delivering dynamic and detailed sound with high resistance to interference. The headphone amplifier circuit uses a two-stage design: the first for voltage amplification, the second for current expansion, ensuring powerful output and pure, nuanced sound quality.

.

Cleaner Sound, Zero Interference

The M21's digital and analog sections are physically separated and shielded, each with its own isolation blanket. This minimizes interference and crosstalk, improving heat dissipation and contributing to a cleaner, more defined sound.

.

Stable and Refined Audio Quality

The M21's audio circuitry uses high-precision thin-film resistors and low-drift capacitors, improving sound coherence across channels and frequencies. Additionally, the DAC and amplifiers are supported by over 10 high-capacity, low-impedance tantalum capacitors, for consistent power reserves and powerful, dynamic sound.

.

Fifth-Generation FPGA + Dual Femtosecond Oscillator

The M21 integrates a fifth-generation FPGA paired with two custom femtosecond quartz oscillators, custom-developed to ensure timing precision and stability. This system ensures a highly precise, low-jitter clock for faithful reproduction of PCM and DSD signals at any sampling rate.

.

Listen Anywhere, Uninterrupted

The built-in 4000mAh high-voltage battery provides up to 15 hours of continuous playback, ideal for extended listening sessions on the go or throughout the day. The 20W PD fast charging support also allows you to quickly charge the device even during short breaks.
