The FiiO JM21 is built for demanding listeners who want a proper portable Hi-Res digital audio player without giving up the convenience of modern apps. Its ultra-slim body and Sky Blue finish make it easy to carry and easy to live with, whether you’re commuting, traveling, or listening at your desk. With Android 13 on board, it’s designed to handle both offline libraries and streaming services in one clean, pocket-friendly device.
Sound-wise, the JM21 centers around a dual CS43198 32-bit DAC architecture and a fully balanced design supported by dual OPAMPs. That hardware approach is paired with up to 700 mW per channel output power, helping it deliver punch, control, and clarity with a wide range of headphones and IEMs—including models that appreciate more drive. Three selectable gain levels let you match output to your gear, while the octa-core Snapdragon 680 platform keeps the interface responsive. With 4GB RAM and 64GB storage, everyday navigation and multitasking feel smooth and predictable.
For long sessions away from a charger, the upgraded 3100mAh battery is intended for all-day listening; depending on volume, connections, and workload, playback is typically quoted in the ~12.5 to 16-hour range. FiiO’s DAPS (Digital Audio Purification System) aims to bypass Android’s system-wide SRC so audio can stay closer to its native quality, supported by a 5th-gen FPGA architecture and dual independent crystal oscillators. If you want a slim Android DAP that prioritizes balanced output and practical performance, the FiiO JM21 is ready—check it out in our store.
