FiiO M21 Digital Audio Player – Pocket-Sized Power, Desktop-Class Sound
The headphone experience is personal, immersive, and endlessly enjoyable. But it only gets better when your source keeps up. The FiiO M21 is built to do exactly that—turn every listening session into a high-fidelity moment, whether you’re on the go, at your desk, or relaxing at home.
Why the FiiO M21 Stands Apart
A Portable Hub with Serious Muscle
The M21 isn’t just another DAP. With quad CS43198 DAC chips in a fully balanced design and output power up to 950mW per channel, it drives everything from sensitive IEMs to full-size planar headphones.
Designed for Pure Musical Enjoyment
Where compressed sources sound flat, the M21 reveals the full richness of lossless and hi-res music. Expect clarity, punch, and nuance—all while keeping the presentation musical, not clinical.
Flexible for Every Setup
Stream Tidal, Qobuz, Spotify, or play from local storage. Use Bluetooth, Wi-Fi, or USB DAC mode. With multiple gain modes (including Super High Gain), the M21 adapts seamlessly to whatever you’re listening with.
