Free of noise

Experience bliss


Enormous performance improvement

Dual DAC design

The left and right audio channels each feature a high- performance, high-efficiency ES9038Q2M DAC to better reproduce every last detail in your music. These DACs allow for decoding support up to 384kHz/DSD256.

The power to truly move you

Qualcomm Snapdragon 660 processor

In the M11S is a Snapdragon 660 with a 4 big / 4 small core architecture, same as in the flagship M17. This allows the M11S to provide a smartphone-like smooth experience for a truly immense performance improvement over the previous generation. Not only can the chip capably handle tasks like watching videos and playing games, it can also ensure ultra-low power consumption when only listening to music for better battery life.

The pursuit of ultimate sound quality never stops! The M11S supports MQA 8x unfolding for master-level sound,   so you can better appreciate the music the way the artist intended.

Audio data is passed through a FiiO-developed 4th-gen FPGA with phase-locked loop technology, which works together with two custom femtosecond crystal oscillators to provide a high-precision and low jitter unified clock source for the entire audio architecture. This is all done in the pursuit of purer sound.

High energy ahead!

670mW high power output

Under a 32 ohm load, single ended power output is 200mW while balanced power output is at a healthy 670mW–allowing the M11S to better take your breath away when listening to music.

With an atmospheric and bold hexagonal structure, the M11S makes a striking impression wherever it goes. The multi-touch 5.0-inch 720p display is perfectly sized for comfort during prolonged usage sessions.

The PEQ (Parametric Equalizer) function was designed for the M11S, which supports 10-band self-defined tuning. On the FiiO Music App in the M11S, users can self-adjust the frequency, gain level, Q value, etc., achieving more accurate frequency response among every frequency range while ensuring high-fidelity sound quality. It supports up to 192kHz/24bit under PEQ style.

*Enable PEQ through the FiiO Music Lab. After enabling, PEQ would replace the default EQ, of which each frequency band can be self-defined.
