FiiO M25 R2R Portable High-Resolution Music Player

ARRIVING OCTOBER 2026

A distinctive take on portable high-resolution audio

The M25 R2R is built around FiiO’s own segmented R2R PRO resistor array. This DAC design gives the player its distinct sound character while preserving the detail and dynamics expected from a high-performance digital audio player. Choose Naturally FLAT for a presentation faithful to the recording or Gently WARM for a smoother, warmer sound.

Power for serious headphone listening

The M25 R2R delivers up to 1,700 mW + 1,700 mW into 32 Ω through its balanced output in Big Ear mode, which activates when a compatible fast charger is connected. In high gain, balanced output reaches up to 1,000 mW + 1,000 mW into 32 Ω. A 31-band parametric EQ and Auto EQ give you further control over the sound of your headphones or IEMs.

Your music library and streaming apps in one player

A Qualcomm QCS6490 processor, 8 GB of RAM, and 128 GB of internal storage make it easy to browse music and use compatible streaming apps. Add a microSD card for a larger local library. The 5.5-inch touchscreen and dedicated physical controls make operation convenient whether you are listening at home or on the move.

Ready for your desktop setup

Connect the M25 R2R to a computer and use its XMOS XU316 interface as a USB DAC and headphone amplifier. FiiO’s Desktop Mode powers the player externally while isolating the battery, reducing charge cycles during stationary use. Its 6,500 mAh battery is rated for up to 14.5 hours of unbalanced or 12.5 hours of balanced playback under FiiO’s laboratory test conditions. Actual runtime varies with use.
