FiiO M21 Android 13 Portable Music Player | Quad CS43198 DACs, Hi-Res Audio, LDAC

The FiiO M21 is an Android 13 portable music player built for discerning listeners who want more from their pocketable audio. Powered by a Qualcomm Snapdragon 680 on a 6nm process, it balances solid performance with smart power use, so you can stream, store, and enjoy a wide library without slowdowns.

Equipped with 4GB of RAM and 64GB of internal storage, plus expandable options, the M21 keeps apps responsive and playlists within easy reach. Android 13 delivers a familiar, streamlined experience for navigating libraries, playlists, and settings, helping you tailor your listening journey to your devices and preferences.

Designed for longevity and clarity

A patented Desktop Mode lets you run the player on external power while the built‑in battery rests. When Desktop Mode is active, the device draws from external power, which can help reduce wear on the internal battery during long sessions at a desk or in a stationary listening setup.

At the heart of the M21 is a robust audio engine featuring four CS43198 DACs in a fully balanced two‑stage design. This 4‑channel, 8‑path architecture offers wide dynamic range and high noise immunity, while the two‑stage amplifier preserves detail from delicate whispers to dynamic crescendos.

Connectivity that adapts to your setup

Versatile outputs include dual 3.5mm and 4.4mm headphone/line connections, each with independent amplification circuits. In addition, SPDIF and USB Audio outputs broaden compatibility with digital gear. SPDIF performance is described as rivaling professional digital transports in jitter reduction, which some listeners may notice as tighter timing and clearer detail.
