Experience studio-grade audio in the palm of your hand with the FiiO M21. Powered by a Qualcomm Snapdragon 680 processor and running a custom Android 13 OS, this sleek device delivers uncompromising high-resolution playback. Dual Cirrus Logic CS43198 DACs and dual SGM8262 op-amps in a fully balanced architecture ensure stunning clarity, ultra-low distortion and wide dynamic range.

Whether you're using IEMs or demanding over-ear headphones, the M21 handles them with ease — its balanced output delivers up to 700 mW + 700 mW, and it offers three gain settings (low, medium, high) to match your gear. Streaming and local playback are elevated by features such as FiiO’s proprietary DAPS (Digital Audio Purification System), dual femtosecond crystal oscillators, and a segmented power supply for purified audio.

Connectivity is rich and versatile: two-way Bluetooth 5.0 supports LDAC, aptX HD, LHDC, SBC, and AAC codecs. In USB DAC mode, the M21 supports up to 768 kHz / 32-bit PCM and DSD512, turning your computer into a high-end audio source. Additional outputs include SPDIF coaxial, line-out (LO), and both single-ended (3.5 mm) and balanced (4.4 mm) headphone jacks.

Despite its impressive capabilities, the device remains highly portable — just ~193g and a slim profile. The 4.7-inch HD touch display gives you intuitive control over your music. The internal 4000 mAh battery powers up to 15 hours (single-ended) or 12.5 hours (balanced) of playback, and the battery is fully charged in about 2 hours via fast charging.

Whether you’re on the go or at your listening desk, the FiiO M21 brings uncompromised hi-fi wherever you are.
