The FiiO M21 is a compact, Walkman-inspired portable high-resolution music player that delivers flagship-level audio in a pocketable body. A 6nm octa-core Qualcomm Snapdragon 680 runs a smooth Android 13 experience, while four Cirrus Logic CS43198 DACs and a fully balanced two-stage amplifier deliver rich, detailed, and powerful sound.
FiiO's Desktop/Portable dual power supply mode lets you bypass the battery with external power for up to 950mW per channel in Super High Gain, turning the M21 into a desktop DAC/amp/streamer. On the go, its 4000mAh battery provides up to 15 hours of playback.
Connect a power source to the POWER IN port and the M21 runs directly from external power with a high-voltage 21Vpp supply, unlocking up to 950mW per channel for demanding headphones.
Four CS43198 DACs and a fully balanced amplifier stage deliver neutral, transparent sound with impressive imaging, plus low-jitter coaxial digital output for external DACs.
Stream from your favorite apps on Android 13, play your local library in Pure Music mode, or use the M21 as a USB DAC or Bluetooth receiver.
