USING THE M3K

The M3K uses a custom Linux OS and as you can see from the above pictures roughly 80% of the 2-inch IPS screen is used for album art (when present of course - may take a couple of seconds to load). The screen may not be very detailed and doesn't feature the same angles most of us are used to with our smartphones but for a budget-friendly music player that was expected.

You can also use the capacitive buttons to browse available files/directories, browse categories, use the high-fidelity microphone to record what you hear, adjust play settings (you can even set the maximum volume level which is quite useful for kids if you are worried they may damage their ears), adjust the system settings (screen brightness and USB mode - DAC or storage - can be adjusted from here) and finally you can also choose one of the two available themes.

If you want more colorful graphics you should choose theme number two as seen above.

FiiO has also equipped the M3K with a 5-band equalizer with 6 available presets (rock/classical/jazz/pop/dance/metal/vocal).

You can check for available firmware updates online and you can also download the USB DAC driver for Windows if you’d like to use it as a sound card.

The driver only allows you to change buffer size so it’s nowhere near to what we usually get from onboard and add-on sound cards.
