It offers 64GB of built-in storage, which is ample for thousands of songs, and runs Android 13 on a powerful Snapdragon 680 processor. This means it can smoothly handle popular music apps, making it versatile beyond just playing stored files.

The player supports high-resolution audio formats and offers versatile headphone outputs, including both standard and balanced connections, plus options like SPDIF and USB audio output for flexible use with various audio setups. Battery life is thoughtfully managed with a special Desktop Mode that helps prolong battery lifespan during extended use plugged in.

On the portability front, the M21 is reasonably compact with a 4.7-inch screen and weighs under a pound, but it’s a bit larger than typical simple MP3 players due to its advanced features. The user interface benefits from the Android system, providing familiar navigation and app access, though it might feel more complex for users who want a straightforward device only for music playback. The FiiO M21 suits music lovers who want excellent sound quality combined with smart features and app support, but if you prefer a very small, simple player or the longest possible battery life without charging modes, there may be easier options.

Audio quality is a major highlight with the ES9038PRO DAC chip, ensuring high-resolution sound, making it ideal for audiophiles who demand superior sound performance. The device also supports various streaming services like Spotify and Tidal, adding to its versatility. Portability is somewhat impacted by its weight (2.42 pounds) and size (5.91 x 3.15 x 7.48 inches), making it a bit bulky compared to other MP3 players, but its ergonomic design and dual power supply (desktop/portable) modes offer some flexibility. The user interface is smooth and responsive, thanks to the Qualcomm Snapdragon 660 processor and Android 10 OS, making navigation and app usage efficient.

Additional features like Bluetooth 5.0, WiFi, and high-res audio support enhance connectivity and user experience. Its price point and bulkiness may not appeal to casual users. This player is best suited for serious music lovers and audiophiles who prioritize audio quality and feature richness over compactness and budget-friendliness.
