（Note: This article is not Fiio M1s review, but it include the full information of Fiio M11 , and the comparison between Fiio M11 and Fiio M9 .
Meanwhile, we will collect all the Fiio M11 reviews right here, so you can read them conveniently）
BUILD QUALITY AND DESIGN
Did you see the pictures? Most likely but they may not be giving justice to how beautiful this device really looks in person. It is solid and hefty. There are no curves to it, just straight lines, which I love. It has an authoritative, powerful look, only tamed by the beautiful golden volume wheel. Buttons are tightly tactile and very responsive, no loose feeling at all. Headphone ports are gold lined and reinforced. Headphone jacks plug in real tight and secure. Notice the thread here? There are no “loose ends” to the build. It is as solid and tight as they come.
Burn-in: It is a DAP, not a headphone where the driver needs to loosen up so I do not expect a lot of changes after burn-in. Approximately 10 hours in and the sound remained consistent, if a little richer out of the box. No other changes noted thereafter.
Fiio Music App EQ is off.
3.5mm headphone out (I have no balanced headphones to test)
Gain is set to HIGH
Filter is set at Short delay Sharp Roll-Off (default)
I would like to preface this section by saying that headphones produce what you hear. The quality of bass, mids, highs, soundstage, and imaging are mostly dependent on the headphones. What a DAP could lend is its inherent leanness or warmth (dependent on the DAC), lower noise, and clean, abundant power, among other features. The role of a DAP is to output as linear a sound as possible to the headphones and let the headphones do the trick. Improvements to the headphone’s inherent qualities may be noticeable due to a better DAC and the added power (vs a phone or other DAPs).
The M11 sound is neither too lean (others may refer to this as thin or neutral) nor too warm (thick or dark). It hits the sweet spot at being lean and detailed with just the right warmth and richness so bass notes come off clean and clear.
I don’t find the need to EQ the default sound of the DAP. It is just right. And if you ever want to EQ it, the equalizer in the Fiio Music App isn’t too invasive, but some may find it as ineffective since some EQs apply an immediate change to sound with a few DBs of adjustment. I think this is intentional to avoid distortion but Fiio could make it a touch more effective.
What it lends to the headphone is better detail in bass notes, mid-range, and treble. Differentiating notes in a bass guitar for example is easier, as well as differentiating vocal types from singers. It’s easier to recognize that a particular singer sings in a particular range or pitch, etc. Vocal uniqueness among singers come in more distinctively. The decay in cymbals and other high frequency instruments are much improved and you wouldn’t normally associate notes with cymbals but a simple mild crash can be very detailed and tingling.
As I prefaced, a better DAC (two DACs in this case), and the added clean power brings about these significant improvements to sound.
The below subjective impressions are made with IEMs including FiiO FA7/ FA1, Final E4000/5000, Er4b and more, 2 days of burnt in are done with earphones attached to the 4.4mm connector.
I am mainly testing under balanced connection for optimized performance and using the default Short delay Sharp Roll-Off digital filter on high gain. Higher resolution /well-mastered tracks with All to DSD mode sounds the best for me on the M11 but it may consume a lot more power than without the function turned on.
The tuning approach on the M11 focuses on the mid-range. The bass is meaty and soft, the vocal is swift/not grainy and the treble is fairly extended. I would call it a safe tuning and I prefer pairing with multi-driver IEMs that has stronger bass textures and lighter impacts.
The bass bleeds into the sub-bass and I am eq-ing down some frequencies in the lows to reveal the sub-bass. The in-app EQ on FiiO’s music app could be handy but with strong hardware, you can enjoy advanced EQ tweaks that require more system power say Viper, to give the low end more power and the dynamics more texture that will boost the overall resolution.
Balanced and Unbalanced
All outputs have no noticeable background noise tested with a silent track. Switching from 3.5 (with 2.5 to 3.5 convertor used) to the balanced connection you will notice the treble being tamed, there is better headroom and resolution as well.
Obviously there is more power and quality with the balanced connection and comparatively, the 3.5mm port sounds more aggressive in the bass region and comes with brighter mid-treble frequencies.
I recommend using the balanced connection for the best quality and the 3.5 will still be useful as a backup. You could also link up to other speakers/ DACs with SPDIF out from the 3.5 socket.
M11 vs X5 MKIII
M11 is the spiritual successor to X5 MKIII so its natural and mandatory comparing the two. X5 MKIII was really cool when it was released, it looked and felt impressive sound was great but not top-notch, at least on IEMs, its performance was plagued by the slight hiss and dirty noise-floor on sensitive IEMs.
M11 is taller, heavier, has an extra headphone out, it is much faster by comparison, offers few additional Bluetooth features and an extra codec, has a stable Wi-Fi connection and a heftier battery life. M11 looks like a grown-up product from every point of view, there isn’t a thing that I really disliked on it.
Sound wise X5 MKIII has a grainy presentation in the mid treble and sounds leaner and polite by comparison, it works better with mid and high impedance headphones where noise-floor would not be an issue.
M11 sounds noticeable wider and deeper, the grain in the mid treble is also gone, replaced by a very revealing treble performance. M11 has also a pitch-black background and doesn’t have a noise-floor even with high sensitivity IEMs. M11 will also reveal just a little bit more out of your tunes, will have more nuance and shimmer. M11 sounds like a trouble-free X5 MKIII where every nay became an aye.
FiiO officially released its latest music player named Fiio M11 along with many smart features. It has a very similar design to a smart-phone, with an 18:9 full-view display, a high resolution of 1440×720 pixels, 312ppi for the ability to display extremely sharp pictures.
FiiO M11 comes with both 2.5mm and 4.4mm balanced jacks, best compatible with high-end headphones and cables on the market. And like the other recent DAP, the M11 plugs into the computer to make USB DAC via USB-C port.
