Accessories & Packaging
The FiiO M6 unboxing results in a TPU clear cover (similar to the one of the FiiO M9 but with a less accentuated dots pattern), 2x screen protectors (one is already placed on the screen and on the back cover) and a charging USB Type-C cable that is also used as the cable for it’s USB DAC functionality.
The FiiO M6 has a gracious small design with an unibody build and round edges that makes it look like a mini-me smartphone.
On the upper right bezel there is a tiny RGB light that indicates the status of the device.
Operation & Control
The FiiO M6 has four buttons and a multi-touch screen (5 finger sensitive) that allows the full operation of the device.
The buttons are placed on the left edge and on the top edge. The top edge has a single button that turns on/off the device and the screen, the 3 remaining buttons on the left edge control the play/pause function, volume +, volume – and skipping tracks.
On the FiiO M6 you won’t find the volume scroll wheel that the FiiO M9 has, but each click of the volume + or volume – buttons provides the exact same precision of control as the M9’s wheel- and it has the same 120 volume steps.
The 3 side physical buttons can, also, fully control the music playing while the screen is turned off, allowing to: play, pause, increase volume, decrease down, skip to next songs, go back to previous song. The operation with the screen off of any and/or all the side buttons can be disabled through the “Key-lock” settings.
The FiiO M6 is a very easy device to control and use, while the touch screen has the same intuitive gestures as many Android smartphones.
FiiO M6 controls:
Top Edge Button:
- Press and hold: Power on/off
- Single press: Lock screen, turn screen on/off
First Side Edge Button:

Construction & Build
Despite the tiny size, the FiiO M6 is a very rugged device with 2.5D glass and an CNC aluminum alloy main body with narrow bezels.
The FiiO design team has done a very good job with the intersecting section of the glass to the metal body with, nearly, unnoticeable seams or bumps.
The FiiO M6 is equipped with an 800×480, IPS screen with 16 million colors and a diagonal size of 3.2 inches – resulting in a density of 292 pixels per inch.
The IPS technology used for the screen of the FiiO M6 provides full viewing angles with no color shift nor distortion.
The brightness of the screen can be manually set with the same Android brightness slider that can be found on any modern Android smartphone.
The user interface of the FiiO M6 has 9 main menu categories (as of firmware v 1.0.0): FiiO Music, File Management, Gallery, Technical Support, Settings, KKBOX, TIDAL, NetEase Music, MOOV.
Being an Android-based device, the FiiO M6 has the same sliding top menu as any Android smartphones but that has been customized to give quick access links to: Settings, Brightness slider, WiFi, Bluetooth, Line out mode (LO, PO), USB mode (DAC, storage), Filter settings, AirPlay.
The FiiO Music App, bundled with the FiiO M6 (firmware version v 1.0.0) is the version 1.0.7 which enables FiiO Link to control the music player from your smartphone – it is needed to use the FiiO Music app on both devices.
The music playback screen informs the: album cover image, song name, play mode, elapsed time, track duration, number of track (x/x). In-depth details of the audio file being listened can be seen by tapping parallel lines icon – information revealed is: file name, artist name, album name, album name, kHz, bits, track duration and file size.
By being armed with the same M7’s chip, the M6 also has similar decoding capabilities, being able to decode files such as:
- DSD: DSD64, 128（“.iso”“.dsf”,“.dff”）
- APE(Fast): 192 kHz/24 bit
- APE(Normal): 192 kHz/24 bit
- APE (High): 192 kHz/24 bit
- APE (Extra High): 48 kHz/24 bit
- APE (Insane): 48 kHz/24 bit
- FLAC: 192 kHz/24 bit
- WAV: 192 kHz/64 bit
- Aiff: 192 kHz/24 bit
- Aif: 192 kHz/24 bit
- WMA Lossless: 96 kHz/24 bit
- Apple Lossless: 192 kHz/24 bit
- LRC – for lyrics

The top edge holds the 3.5mm headphone jack (on the left corner) and the bottom edge has the USB Type-C connector centered.
The right edge holds the microSD card slot which, unfortunately, gets covered by the TPU cover, so to remove or swap microSD cards on the FiiO M6 you will have to remove the TPU cover – the FiiO M9 has a smarter cover that has a cutout on the microSD slot place so that the card can be removed while using the cover.

During our soundtests, the FiiO M6 revealed to be a neutral sounding music player that was able to reproduce each frequency range as it is meant to be.
Furthermore, we measured it’s frequency response, which resulted in a remarkably flat curve.
As the unit also oofers Bluetooth connectivity and USB DAC functionality, we proceeded to test it out in these 2 modes.
The results of the FiiO M6 soundtests, in Bluetooth and DAC mode, demonstrated that the device is still able to preserve the same impeccable response as in wired mode, with no coloration and only a rolled-off response on frequencies near 20.000Hz while being used in Bluetooth mode (not in DAC mode), which did not affect significantly the sound quality of the music player.
Being that the device provides 9 EQ presets we proceeded to measure their efficiency and response. The results showed that the FiiO Music app EQs reflect the real band’s +dB and -dB applied on each EQ preset with accurate precision.
Additional Audio Options/Settings
- Output selection: PO, LO
- Digital filter mode (fat roll-off, slow roll-off, minimum phase)
- Wireless playback quality: codec can be selected among 6 options
- Balance: 10 levels
- In-line remote on/off
- Balance boost on/off
- AirPlay on/off
- USB DAC on/off
Part of the M6 sound capabilities to highlight include a wide frequency response range of 10Hz to 85000Hz, a recommended headphone impedance of 16 to 100 ohm, measured signal to noise ≥118dB , noise floor <3uV and a power output of 110mW (16 ohm)
The strong output at 16 ohm and 32 ohm allowed the FiiO M6 to drive nearly any in-ear and over-ear headphone with these impedance range without any issues and providing as much power as needed. Moreover, this tiny music player was able to drive full sized headphones with higher impedance with a very respectable performance and output volume.

The FiiO M6 has a 10 band EQ that goes from -6dB to +6dB and covers the following frequencies: 32Hz, 62Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz and 16kHz.
The EQ of the FiiO M6 can be manually set or can be selected among predefined presets (Pop, Rock, Dance, Blues, Metal, Vocal, Classical, Jazz)
