FiiO M3K Overview

  • 1Description

Gain the convenience of mobility without sacrificing audiophile-quality with the M3K Portable High-Resolution Lossless Audio Player from FiiO. The M3K has been engineered to deliver extremely clean, high-resolution audio thanks to the Ingenic X1000E SoC and AK4376A DAC. The Ingenic processor also features low power consumption, which helps the overall battery life of the M3K, which is 24 hours per charge, and up to 38 days of standby time.

When loading up your M3K, you don't have to worry about converting file types, because it supports nearly every popular format, including PCM, DSD, FLAC, MP3, OGG, CUE, LRC, and more. For PCM audio, the M3K can play back in 384 kHz/32-bit quality. All of this is packed into an all-aluminum unibody construction with a 2" tempered glass IPS TFT screen and a capacitive touch interface for navigation.

High-Fidelity Recording
Want to record the voice of a loved one, or an important speech or event? Put the phone away and use the M3K's built-in microphone to capture memories in audiophile-quality. All you need is a microSD card.
A/B Track Comparison
With the M3K, you can use its audio prowess to really dig into different tracks to find the subtle differences. The M3K lets you compare and repeat between two different tracks of your choosing, to hone in on their variances.
Doubles as a USB DAC
The M3K has the ability to let you use its high-quality DAC on Mac or Windows computers to improve the quality of the audio files they can play. For a Mac, simply plug it into a USB port and the FiiO will automatically be recognized. For a Windows-based PC, you just need to install a driver from FiiO to get up and running. Once connected and working, you can play up to 192 kHz/24-bit audio.
File Type Compatibility
The M3K can handle many different audio formats and file types. M3K supports PCM, DSD, APE, AIFF, FLAC, WAV, MP3, WMA, OGG, M4A, ALAC, ISO, DFF, DSF, CUE, and LRC.
Device-to-Device OTG File Transfer
If you use an (optional) USB OTG cable and connect the M3K to a USB OTG-compatible device, such as an Android smartphone, you can quickly transfer music and other files between devices. Note that this feature is not compatible with iPhones, and does not support all Android smartphones.
Sophisticated Design
The M3K features a seamless, all-aluminum unibody construction with tempered glass, which equates to a stunning look that is also extremely durable.
Capacitive Touch Buttons
The M3K utilizes capacitive buttons and a touchpad for operation. There are five sets of touch buttons that are designed to make getting around the UI easy. There are next/previous track, confirmation, back, and menu keys. The touch buttons are also backlit to help enhance usability in dark areas and make the M3K much easier to use when the screen is off. You can enjoy both more convenient operation while enjoying huge power savings from the turned-off screen.

    Rated 5 out of 5 by from Great Little Player I’ve only used it for a day but it seemingly does the miraculous. It plays all my ALAC files, has a decent user interface, a reasonably good little DAC in it, and a real headphone jack. Amp is powerful enough for my sub-100 ohm phones. Not enough for my 300 ohm phones but I didn’t expect that. It’s a whole lot of player for the almost disposable low cost. Highly recommended.

    Rated 1 out of 5 by from garbage This player is the lowest quality gadget ive ever had. the only pro of this little garbage is its size which is a far cry from shanling m0, but still its much smaller than most of really good players. the menu is so laggy that only windows 95 installed on i286 could be as slow. the main feature of this little trash is its ability to not only introduce gaps into otherwize gapless recordings, but also insert a few seconds of the next song surrounded by additional gaps in between the last somg and the next song. fiio could have afforded to hire an english speaking person to translate some menu items not to look so stupid, although it wouldnt have helped with its uselessness. theres a menu item called playback gap with values to choose from gapless and off. whatever you choose, it introduces gaps in between the songs. I regret I bought it, as I couldve bought f. audios much better model for less...

    Rated 5 out of 5 by from Nearly The Fiio M3K DAP is an amazingly good sounding music source with a couple two-three UI issues. At $70 you get a very recent [and remarkably good sounding] DAC. Better still, you can use that DAC with a USB source. My I-Mac links up with the M3K without any additional set-up beyond selecting the M3K in system preferences. However, there is no line out option. As regards playback with my home or car stereo, this doesnt seem to be such a big deal. But the little player doesnt seem to play all that well with outboard headphone amps. Linking the M3K to my Schiit Magni III degrades the sound  a touch. I dont find the inclusion of a recorder helpful, theres no option for recording save with the built-in microphone, which is not exactly a U-47. The biggest problem with this player is the user interface. Its a variation on the UI of the Fiio X1. The X1 has a wheel to scroll through the playlists and song lists. The M3K replaces the buttons and scroll wheel with primitive touch sensitive controls, kinda erratic. If I were to design a Fiio M4K Id dump the recorder, have a line out and have a fully functional touch screen with easier navigation. Ill bet an additional $50 would cover that. The sound, on the other hand, is remarkable. The upper registers are the main feature, smooth, detailed and refined, about as clear a reproduction of the upper octaves Ive heard from any digital source. The deepest registers are a little weak  compared to the Fiio X1s line out connected to the Fiio 12a or Schiit Magni III. But it is properly balanced down there, and everything above 100hz makes up for the lack of dynamics and punch down there. Compressed files sound good, uncompressed files are considerably better.  The built-in headphone amp is fine with my Sennheiser Urbanite XL and 579 headphones, even better with my Klipsch X11i earbuds. My AKG K167 phones need more power than the M3K can provide. This product makes up for its lack of power with a really low noise floor. The form factor—really small and very clean looking—is wonderful. No problem slipping the player into my front pocket. Theres a few buttons on the side for adjusting volume, skipping tracks, pausing and powering down the player. In closing, a really good product that could be better without too much effort.

    Does this charge via USB? If so, can it play music while plugged into a USB/wall outlet adapter?

    Yes. It does not play music through the USB. If used as a DAC with my i-Mac, it charges while playing.
