Multifunction output jack with SPDIF

Through the single coaxial output jack, you can connect to speakers, amplifiers, and decoders using the appropriate output (coaxial, optical SPDIF, etc.)

Global ALL TO DSD functionality for a riveting experience

You will only truly know what is the definition of immersive after hearing this. When using All to DSD mode, any PCM audio signal is converted to DSD, and then decoded to analog as a DSD digital signal – which results in a different, yet clear sound. And not just the built-in FiiO Music app supports this mode – all apps that can run on the M11 Pro do too.

The M11 Pro contains an all-new 10-band dynamic EQ capable of increasing or decreasing each band by 12 dB. With the built-in pop, blues, classical, jazz, rock, dance, metal, and vocal presets as well as a user-defined custom EQ, you can get your music to sound exactly the way you want it.

Hi-Res Audio Wireless certified

Besides having received the Hi-Res Audio certification from the Japan Audio Society, the M11 Pro is also Hi-Res Audio Wireless certified – so you can be sure of the strength of its wireless audio capabilities.

With the fully balanced THX AAA amplifier, the sound quality just gets even more amazing. The op-amps that are a part of the dual THX AAA-78 balanced amplifier architecture deliver extremely powerful output to easily drive most headphones. And using the same power supply, compared to typical amplifiers the THX AAA amplifier gives a more powerful output while being more efficient, resulting in less noise and distortion for a more precise yet natural sound.
