Very simple download the update to a Micro SD card and push the on button and the volume up at the same time. It should engage and update itself.
Latest M3K firmware at the time of this writing was FW1.2.1

Another in the little dap that could global line up which seems to be one of the audiophile themes for 2018.
The FiiO M3K the latest and most diminutive in the recent line up of releases by FiiO is a mysterious wee dap that is lightweight and controlled via a slider that is easily manipulated and well placed.
After reviewing the FiiO M7 and quite some time ago now the original M3 I was not sure what to expect. FiiO has come quite a long way from the earlier daps which were a bit dark and enclosed for me, and now seem to be hitting their stride in presentation and performance.
I did think the FiiO M3K would be an easy review, just drop it below the M7, echo some of that review and dial it back a bit to fit within the price difference. lazy for sure, preconceptions, yes true also. The small M3K had a few tricks up its sleeve and surprised me, but I should have already expected that from other little daps I have tried this year.
A simple player with a usb dac function. That should be enough to keep some happy. No Bluetooth, and no touch screen or wifi. Do not get me wrong, I am not simply pointing out what it lacks, but what it is. A simple stripped down player, one that functions beautifully I might add.
It seems to have enough power to make most portable earphones and head phones perform well enough.
The DAC inside is fairly decent too.
Excellent battery life and stand by.
There are many other small players that have been released onto the market in 2018 and one does really have to be firm in what they are seeking and what functions they personally require in making their final decision on which precious to possess.
Luckily FiiO has many daps and dac/amps in their product line up, each with an array of functions, so there is one fiiO product to fit the need for about everyone I the M3k isn`t your cup of tea.
The FiiO M3K player, perhaps one for the younger phone less set, or for one who can not take a phone to school or work, for casual listening around the home, taking a walk, working out or as a dac for the computer whilst on Facebook or catching up on some work.
Sometimes the old adage is true...simple is best.
