Powerful Dual DAC Portable 

With dual ES9038Q2M DAC chips, an 8-core Snapdragon 660 processor, and a 5300mAh battery, the FiiO M11S is a powerful, audiophile-grade portable music player that lasts all day–and then some.

Dual DAC design

Each of the left and right audio channels feature a high-performance, high-efficiency ES9038Q2M DAC to better reproduce every last detail of your music.

Fourth gen FPGA technology

The audio data is passed through a FiiO-developed fourth-gen FPGA with phase-locked loop technology, which works with two custom femtosecond crystal oscillators to provide a high-precision and low jitter unified clock source for the entire audio architecture.

Audiophile-grade power supply

The amplifier and op-amp sections of the M11S are independently powered and isolated from each other, ensuring clean and abundant power while resulting in better dynamics.

Free of noise

Thanks to meticulous and careful design refinement, the M11S has a low noise floor of 1.8uV, 62% lower than the previous generation.

Wide variety of audio connectors

The M11S provides 2.5mm, 3.5mm, 4.4mm and a balanced line out, allowing you to connect to your music however you wish.

The power to move you

The Snapdragon 660 boasts an 8-core architecture, same as in the flagship FiiO 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 handle tasks like watching videos and playing games, it can also ensure ultra-low power consumption when listening to music.

14-hour battery life

A large 5300mAh battery with lots of power gives you peace of mind. With support for QC 4.0 and PD fast charging, it only takes 3 hours to fully recharge.
