Given the rapid development of DAPs in the last 2 years, it is totally unsurprising to see FiiO launch a revised edition of their original and very successful X7 flagship DAP which launched in late 2015. FiiO has always been consistent in a product life cycle of around 18 months and the TOTL DAP cycle seems to be no different.

FiiO also has a habit of dovetailing their products with a defined vision and very often they lead to the market with a new product feature, that if successful, find themselves integrating into succeeding products.

It is not simply a trickle down effect either. The $649.99 X7 Mark II draws a little from its little sibling, the X5 Mark 3, both in terms of firmware and design concepts. Some of what you see on the X7 Mark 2 has been refined from earlier X5 Mark 3 customer feedback.

It is also one of the lead products for FiiO’s Infinity sound marketing campaign that has seen it launched simultaneously with other co-branded FiiO gear including the X3 Mark 3, F9 and Q1 Mark 2. Whether or not the Infinity sound concept will take hold or not it is too early to tell but clearly, the X7 Mark 2 is the big ticket item and as such should have all the best “goodies” under the hood.

What Is The Pitch?

New DAC

There are a ton of unique selling points on the new X7 Mark II but a few strong pitches stand out for me to lead off with. The first and foremost is the new DAC chip set that now seems to be the standard setter for high-end DAPs, the ES9028PRO.

I am a big fan of this chip set thus far in the implementations I have heard to date, be it the DX200 or the Oppo Sonica’s slightly higher end ES9038PRO. Though the X7 Mark 2 only deploys a single chip implementation unlike the dual DX200 design, the performance figures and tonal change up from the ES9018 chipset should provide a vastly superior though still neutral sound and one fixed on delivering plenty of detail. Worried about treble glare, an often remarked tonal quality of the ES9018, then the Es9028PRo so far has been the antidote to those concerns.

The fact that the material cost of the ES9028PRO is considerably higher than the ES9018 yet the older FiiO X7 price point has been largely retained be considered a very positive plus point.

New Amp

The X7 Mark 2 also comes shipped with a brand new amp module, the AM3A, which is a single ended and balanced output amp card in keeping with FiiO’s Infinity Sound pitch.

The AM3A features an Analog Devices AD8620 opamp implemented to provide a higher level of performance than the older AM3, particularly with sensitive IEMs. If you remember the AM3 had a slightly high noise floor, this new card drops the output power a little in favor of a much and more attractive lower noise floor for IEM users.

Modern Shape

Gone are the more sedate straight lines of the older X7 and in comes the new left panel accented rotary volume dial design of the X5 Mark 3. This now harmonizes the design cues between both DAP lines as well as offering a more tactile and easier to use volume control experience that brings it up to speed with today’s typical competing DAP designs.

FiiO also claims it should be a little easier to use than before with a slightly lighter weight and a little height and thickness taken off the Mark II.

Enhancements

Everything else is being pitched as being faster and easier to use (streamlined OS plus 2GB RAM), easier to connect to the outside world (improved WiFi and BT support), more output functionality (additional optical output), and capable of storing a lot more music and files than the previous model (dual memory slots).

Build

Form Factor

The X7 Mark II uses the same titanium colored CNC Machined aluminum alloy as its predecessor, however, the final design has been given a more modern finger and case friendly makeover.

Handling

It may not seem a huge change but once in your hand, you will notice the smoother handling of the X7 Mark II over the Mark 1. A big contributing factor is the reworking of the volume buttons into a 45-degree etched line rotary dial on a more modern accented left control panel.

With all the buttons on the left panel, there is now also less stretching and manipulation to use the playback controls on the Mark 2. Combined with a rounded redesigned leather case you get a softer level of pressure in your hand as well as a device that is generally much easier to operate.

Left Panel

The left panel is also a harmonized design originally show cased with the FiiO X5 Mark 3 and represents a more modern approach consistent with competing DAP designs in today’s market. The only major difference in how they are implemented is the final part of the wedge design over the amp card which is actually a separate piece screwed in. This allows you to use the older amp cards with their older shape without affecting the form factor. You simply take off the wedge and screw it back on again over the amp card of your choice.

Dimensions & Weight

The X7 mark II is still more or less a candy bar design though this time we lose 1.2mm in length and 1mm in thickness as well as 10g in weight. What the marketing material does not say is the additional girth over the older X7 with that new left panel design. The X7 mark 2 may be shorter and thinner but it is wider by some 3.2mm. In terms of preference, I trade height for width since in the hand the X7 Mark II feels more balanced than the older longer X7.

 HeightWidthDepthWeight
FiiO X7 Mark II128.7mm67.2mm15.5mm210g
FiiO X7 Mark 1130mm64mm16.6mm220g
iBasso DX200128.5mm69mm19.5mm240g
Opus#3117mm74mm18mm220g

The Mark 2 is not the shortest of the competing DAPs, that award goes to the Opus#3 but it is certainly not as fat or as heavy. In fact, out of the selected DAPs, the X7 Mark II was the lightest and thinnest DAP tested. The numbers may seem marginal on a ruler but in the hand, they make a huge difference.

Back Panel

This is the other major design change and a most welcome one also and that is replacing the raised back panel with a flatter version.  Though not a huge factor in the operation functionality it does improve the visual aesthetics immensely as well as increase the fit and grip from the included leather case. Much of that reduction in height being pitched in FiiO comes primarily from flattening the back panel.

Screen

Performance

On paper, FiiO has deployed the same screen specs from the gen I X7, a 480 x 800 pixel 3.97″ IPS TFT screen capable of 16.7m colors and a 233ppi pixel density resolution.

In reality, the performance of the screen on the Mark II is much superior with better color saturation and more pop so they have definitely changed to a better performing version than the previous Mark I LCD screen.

It is not quite on the same level as the brilliant DX200 screen which is a bit bigger at 4.2″ IPS Screen and a slightly higher resolution of 768 x 1280 but a bigger screen would have meant a much bigger body which may not have suited FiiO’s harmony design philosophy.

Flush & Bezel changes

If you also look carefully the screen is now more flush with the chassis compared to the older raised screen of X7 Mark 1 and the bezel design has changed a little also. This is primarily due to the slightly squatter form factor with a thinner top bezel and slightly thicker bottom and side bezels.

FiiO has also moved the “FiiO” white moniker off the bottom bezel border to the back plate. I suspect moving it creates less distraction when watching movies and media given its all white appearance.

There is still no integrated navigation in the bottom bezel, something smartphone makers are really going to town on. It would have been fascinating to see a borderless X7 screen design, perhaps Gen 3?

Blue LED Lights

You still have the very funky LED light system on the Mark 2 just below the screen which will show a pulsing blue light for power on and charging. The option to customize the light to solid or pulse remains in the display settings should you wish to differentiate.

Memory Capacity

The X7 Mark II not only draws from the X5 Mark 3’s form factor but also its memory card function and capacity. Instead of one open slot on the left side of the old X7, the Mark II now sports 2 sim slot style trays that can hold up to 512GB in total (256GB x 2).

On top of that, the internal memory gets a boost from 32Gb to 64GB. The switch to these sim tray style slots is similar in styling to the X5 with a 0.2mm gap but you do need to keep a pin or the key card handy if you want to open it up and change cards.

Battery Life

Battery size has increased from a 3500mAh to 3800mAh on the X7 Mark 2. FiiO has rated the X7 Mark 2 capable of delivering 8 hours battery life in single ended mode and 7 hours in balanced output though in truth this relates more to the performance of the new AM3a amp card as opposed to just the X7 itself.

Amp Card Influence

Previous amp cards all have an effect on the output rating and battery performance of the X7 system. You can get as low as 6 hours with the balanced output of the slightly more powerful AM3 card on the older X7 and as high as 9-10 hours on the weakest output card, the AM1.

The AM3a, therefore, sits second from bottom in terms of battery life but its performance is not inconsistent with its output ratings. Much of the additional battery life of the Mark 2 is likely to be used for the additional oscillators, RAM and CPU demands.

Rapid Charging

One thing to note with the Mark 2 battery management is that it supports the same rapid 9/12v charging system on top of the regular USB BC1.2 design found in the X5iii. This means you can charge your X7 Mark II in about 1.5 hours rather than the more standard 2.5 hours. The new battery config allows both this and temperature management when opting to rapid charge and tells you all of this on the screen during those 1.5 hours.

Physical Controls

Inputs & Outputs

Optical Output

There have been a few notable changes and additional features to the Mark II I/O’s over the first generation design. The big new feature is the addition of an optical output to the jack on the top plate. This is a ‘do it all’ jack now for both analog and digital line outs with both line and coaxial from the previous design still being retained. Those who own a Hugo, Mojo or even a lower end iBasso D14’s can now use the X7 Mark II’s optical output as well as the USB OTG and coaxial features.

Micro USB

One thing that did surprise me was the retention of the micro USB slot for charging, DAC and OTG purposes. Since quite a number of releases in the last 12 months have gone to USB-C I was half expecting the new X7 to go in the same direction. Sure micro USB is still quite prevalent and connection options are as easy today as they were 18 months ago but I get a feeling this maybe less future proofed than before. Time will tell.

Power button

FiiO has also moved the power button away from the left panel to the top panel and drawn again from the X5iii design though it omits any LED given it already uses the LED strip on the front panel. I actually much prefer the position of the power/Screen button on the new X7 over the X5iii. It stays out of the way a bit more whereas the X5iii position tended to conflict a little with the play pause button on the opposite side. Too many times I have hit the play pause button with pressure when attempting to press the X5iii power button so the new position is ideal.

Playback Controls

Playback controls are now all housed in the left panels wedge panel design with a rotary dial replacing the older volume rocker of the X7 Mark I. This is the exact same design and layout of the X5iii with slimmer playback rocker below the rotary dial and the play pause button just above.

Personally, I am a big fan of the new playback control system and it felt right on the X5iii. Everything feels more tactile now with the buttons a little more raised and the volume rocker in-between and all on one panel. Controls are easier to find, faster to access and less left to right-hand manipulation in the process.

Accessories & Packaging

The X7 mark II retail box has had only a few minor changes from the original X7 box 18 months ago. It is marginally bigger and wider with a pic of the new design as well as apt-X in bold white letters on the back, something which the X7 did not have when launched 18 months ago.

New Cases

Perhaps the best part of the new accessory package is the included case. The original X7 did not have one, you had to buy it, though it was a lovely brown color. It also slid off way too easily after prolonged use.

The X7 Mark II now comes with leather case as standard and is better designed to hold the X7 Mark II in place with slots for rotary control and digital outs as well as indents for playback control. It pretty much draws from the design of the X5iii case with the red leather sticking on the back.

This time the playback button is covered by the case and the top seam is open by design I presume to allow for the case tension surface on the left to be a bit looser for accurate button mashing.

Everything else is relatively similar to the older X7 accessory kit with a screwdriver for amp card swapping, USB-A to micro-USB charging cable, coaxial adapter, warranty and quick start guide. Note though the screwdriver is much bigger and easier to use than the older T5 screwdriver in the X7 Mark 1 package. I dare say a few of those tiny T5 versions have been lost over time.

  • Interesting to touch it & compare with Samsung 7 Edge

    • headfonics

      Both very different devices though.

  • R.H.

    Would you say the treble is linear like the rest of the spectrum? I want something accurate and I’m hoping the x7ii isn’t bright sounding at all. Coming from an LG V10 with lower treble I find a bit shouty and louder than the rest of the mix. It’s probably from the es9018k2m inside. The 9028 in the x7ii fixes this?

    • headfonics

      More refined than a V10 for sure, much of that is more due to the weaker amp in the V10. The old es9018 had a bit of top end glare, the ES9028PRO resolves that without loss of sparkle.

  • Marcelo Paciorek

    Thank you for your review! I just wonder if its cappable of streaming spotify.

    • headfonics

      Yes, it can stream Spotify.

  • Yevgen Chupak

    Marcus, let’s be totally honest here. Hardware is great on mll. But software… It’s the same nightmare that all ml users have. One can go to fiio forum and check it with your own eyes.

    Since 2015 fiio was unable to create good firmware. Still the very much same bugs as it in 2015. Dac delay problems. Stream freeze. Tidal hangs. Constant crushes in android mode… Etc…

    Don’t get me wrong… If all you need is just to push play button and listen for you dsd files it will good player both original and mll. But if you bought it to use it at its best then look elsewhere.

    Btw x7 and x7ll using pretty much the same firmware all problems that users of original x7 you can find in mll.

    Hope this review will be useful and people will think twice before they will jump in fiio android players train. 😒

    • headfonics

      It’s good to see you again Yevgen and I know you do not like FiiO software from our last chat 🙂

  • Werner Walter

    As always great review Markus.Please correct me if I am wrong, but I interpret after reading it: the new AM3A in unbalanced output, do not match correctly with headsets a bit demanding like the AKG 712 PRO (62 Ohms / 105 Db, I own) . And that for it, should combine the Fiio X7 ll, with another amp. Or maybe think of an X200 (something more expensive) or definitely give up a very good sound, and go for a sufficient volume with a Fiio X5 III. From where I live I can not access to compare them, and I can ONLY choose the best option through your advice. THANK YOU !!!

    • headfonics

      I think yes for something like the 712 which is a bit more thirsty I would advise balanced AM3 or AM5 amp cards. Balanced on the AM3a though might work but if its just headphones then safer with a more powerful card.

  • Gobta Sui

    Hi, i have a galaxy s8 (exynos) along with spotify and tidal subcription. I got both the mojo and OPPO ha-2 se. I dunno if i should get a DAP and if i should maybe just go with lower tier ones as i will be using extenal DAC?what do you advise?I work at a desk so no commute

    • headfonics

      I think your setup is perfectly fine to be honest, no need to change to a DAP.

  • ductrung3993

    Is this significantly better than than the Cayin N3 at driving IEM?

    • headfonics

      It’s significantly different. The N3 on low gain is quieter and very impactful like a mini i5. However, it is not as resolving or detailed as the X7II. The N3 does not offer balanced or a wide range of features. Don’t get me wrong though. If budget is tight the N3 is a killer DAP.

  • PaulJM

    Does it support download in Tidal ?

    • headfonics

      Just asked FiiO as TIDAL is not in our region and their answer is yes you can.

      • PaulJM

        Thanks for following this up. Will be interested to trial in the store, as no other players appear to do so, even A&K

  • Arjun M

    Great review! I want to know whether this sounds better than my LG G6 with ESS Sabre Quad DAC chip?? If yes I would definitely get x7 v2!

    • headfonics

      The G6 is probably the best-equipped smartphone out there today in terms of DAC capability. However the amping is nowhere near as good as the X7 v2 and all its various possibilities. This the G6 lacks the dynamic range and resolving capability on an amp per amp basis compared to the X7 Mark 2.
