True R2R DAC in a portable form

FiiO’s first portable implementation of a true R2R ladder DAC translates desktop‑grade sound into a compact player. You’ll find two sound profiles: FLAT for a neutral balance and WARM for a more analog‑inspired feel. The result is a flexible palette to match genre and preference without extra equipment.

Designed for vivid visuals and ritual listening

The 5.5‑inch Full HD touchscreen invites engagement with cassette, spectrum, and VU meter themes that give you a tangible sense of the music as it plays. The display enhances navigation and makes EQ adjustments feel like a ritual rather than a setup step.

Smart tuning and powerful output

AUTO EQ automatically matches headphone frequency curves for precise tuning. In addition to AUTO EQ, there are preset and manual EQ options to tailor the sound. The fully differential TI analog circuitry drives headphones with authority, delivering up to 1100mW per channel on the balanced path.

Why this matters for everyday listening

Whether you’re testing new IEMs or enjoying familiar gear at volume, the combination of high‑resolution DACs, robust processing, and a portable, user‑friendly interface means you can explore your library with fewer barriers. It’s about hearing more of what you love with less fuss, and having the option to adjust the tone as you discover new tracks or playlists.
