It comes with 64GB of built-in storage, which is enough for a large music collection, and runs on Android 13 with a Qualcomm Snapdragon 680 processor for smooth operation. The 4.7-inch screen offers a decent size for navigation and viewing song info, though it’s not the highest resolution compared to some competitors.

It supports a wide range of file formats, including Hi-Res Audio and DSD, and includes versatile output options like dual headphone jacks and SPDIF for connecting to other devices. Battery-wise, it has a unique Desktop Mode that helps extend battery life when plugged in but does require a 9V battery included with the device.

The user interface benefits from Android 13, meaning you can use popular music apps easily, though the learning curve might be slightly higher than simpler MP3 players due to its advanced features. The FiiO M21 is well suited for music lovers who want excellent sound quality, solid storage, and flexible connectivity, but casual users looking for ultra-long battery life or a simpler interface might find it a bit complex.

However, there are some drawbacks. The device is quite hefty, which might make it less portable for on-the-go use.
