Review: Fiio X5 Second Generation Part 1

The scroll wheel is still mechanical, and on this review unit has a very smooth glide with very little play. In a lot of ways this feels very similar to my original X5. I would have preferred a slightly stronger tactile response similar to the X3ii – and Fiio says that the final units will indeed be changed for firmer more tactile feedback. For those who have been annoyed in the past with the inaccuracy of the wheel – one click still does not equal one menu movement. It is what it is – and I still have no issues with navigation personally. If you’re someone who has a pet hate with the Fiio wheel navigation system though – there hasn’t been a lot of improvement.

The ports are once again excellent fitting – very snug and secure for jacks.   All connections feel very solid. Supposedly for the X5ii, these ports now have a hard plastic sheath – rather than full metal. I’m not sure if this was for implemented for durability, better connection, or something else – but I’m pleased to report that they are firm fitting.

There are two ports in the top of the unit – the headphone out, and a dedicated 3.5mm line out which also doubles as a digital plug (works with a 3.5mm to coax adapter – which Fiio supply). The second port switches between line-out and coax-out by software switching (in the System Setting Menu). And this is where I come to my first major critique of the X5ii. Normally (on all Fiio’s other DAPs), the headphone out is on the left, and the line-out/coax out is on the right. For the X5ii (and I have no idea why they changed this), it has been swapped. I have already had a couple of mishaps with this, and all I can say is thank goodness I was using HD600’s both times. If I’d had sensitive IEMs suddenly plugged into the line-out, and full fixed volume blasting in my ears, I would not have been happy. This is one change which will take a while for me to get used to – and I guess the obvious question is – why? If it’s going to be a wholesale change across the line-out, I’d get used to it quickly – but the X3ii is directly the opposite. I’m afraid this is one design change that I simply don’t agree with. Not clever.

On the bottom of the unit are dual micro SD ports – which currently handle up to 128Gb cards – so total known capacity at time of writing is 256+ Gb. But Fiio is confident that there should be no issues handling larger capacity cards as they are released, so expansion options look good for the future. The slots this time have no covers – and I actually think (after some of the comments about the original X5) that many will welcome this change. Nestled between the two slots is a standard USB micro socket for data transfer and charging.

On the left hand side panel of the unit is the on-off switch, and below that the volume buttons. There is decent separation between the power and volume buttons, and the volume buttons protrude very slightly more from the unit – so they are easy to identify. Tactile response is pretty good. I understand Fiio is going to change an internal piece of silicone (to improve tactile response further). The power LED light is now in the center of the power button, and this is surprisingly effective. It’s blue when active, red when charging, green when fully charged. I like this more than the pinhole LED in X3ii and X1. There is a hole in the protective case to allow the light to be seen.

One thing I’ve noticed is missing from the X5ii is no hard-reset button/hole. Joe informs me that you can activate a hard reset by holding in the power button for 15 seconds though.

The screen is a 2.4 inch HD colour IPS screen with a resolution of 400×360 pixels. It’s hard to make a direct comparison with the original X5 (because I’m running a different community supplied theme), but just looking at album covers, with both units on full brightness, and I would say they are comparable. Both are far more detailed and vibrant than either the X3ii or X1. Viewing angles are very good, detail is sharp, and I personally have no problems reading the screen, even in direct sunlight.

So overall – the build and physical design for me is a pretty solid 7/10. I think the added tactility of the buttons, and the improvement of the wheel (before final release) will bring this score up to almost perfect. And again, the only design change I really question is the swapping of the output port locations.

UI (USER INTERFACE) / USABILITY

Please note that this is with the released firmware 0.05 beta.

Let me preface by saying that if you’re familiar with the user experience of the original X5, X1 or new X3ii, this is going to be very familiar ground for you.

On starting the X5ii, you are greeted with an animated “welcome” screen – before moving to the menu. The menu can be navigated using either the scroll wheel or buttons. At the top of the menu is a status bar which shows (left to right) : volume, gain, current screen (or EQ status if in now playing screen) , micro SD card status, sleep timer – if set, play/pause status, and battery level indicator.

The main menu choices include: now playing, category (or library access via tags), folder browsing mode, play settings, and general settings.

The general settings screen is very straight forward, and includes:

  • Language
  • Update media library manually
  • Lockscreen settings
  • Screen timeout and brightness
  • Power off and sleep settings (including a sleep timer)
  • Software switch for line-out vs digital out via coax
  • Switch for displaying tile or file name (now playing screen only)
  • USB mode switch (USB or DAC mode)
  • In-line microphone control switch (on or off)
  • Theme controls (5 options)
  • Info about the X5ii and options to format the SD card, and totally factory reset your X5ii

The lockscreen switch includes 3 options which should suit most users. I’ve been using lockscreen 3, and have had no issues with random presses while it’s been in my pocket (YMMV).

Theming has a choice of 5 preset themes. I have to admit, I’m not overly keen on any of them (sorry Fiio) – but the ability to mod the firmware and change the graphical appearance, and store 5 different options is going to be very welcome (considering some of the excellent mods so far on the original X5). At the moment I’m using the 2nd theme. Just a note to Fiio here – considering the high quality of the original X5 mods, a competition for modders would be an excellent idea, especially if the top 5 themes could be included in a later firmware option !

Updating the media library can be set to automatic or manual (I always leave mine on manual – as most of the time now I simply use folder browsing). To give you an idea of the time to update an entire library – I currently have 5652 tracks (in FLAC and DSD) on it at the moment, across two cards, and it took 2 minutes and 20 seconds to scan the entire library, but then a further 2 minutes 20 seconds to write the index to memory/card. I trialled this twice and it was pretty consistent both times. Once again though – using manual updating means you update when you have the time. The rest of the time there is no scanning and the X5ii is always instantly ready to use.

I also threw some additional files on to check if the 5800 file limit is still there, and thankfully this limit is gone.

      Volume has no effect (as it shouldn’t – being a fixed line-out). I’ll get Lieven to answer on the gain as I honestly can’t remember, and the X5ii is currently on tour in NZ.

      I think I understand the UI from reading this, but just wanted to clarify the search. I have all my tracks on i-devices (w/o folders) named as “Artist – Songname”, and tagged the same way for sorting in the music player. So on the i-device, to go instantly from “Lecrae – Falling Down” to “Julia Holter – Boy in the Moon”, I press the “J” button** and do a 1 to 2 second scroll and there I am. So with the FiiO, would you have to first change folders and then scroll? I wonder how long it would take to do what I described?

      **Actually when I need Julia etc. on the i-device, I usually press “K” and scroll backwards, since it’s closer.

        Hi Dale. There is no search function as such – I simply use folder view, with a hierarchy system to make the scrolling a lot less. So I have things folder sorted alphabetically into groups of 3 (A-C, D-F, G-I etc) – so 8 first level folders. Underneath that is the artist folders. Under those are the album folders. I have around 400 full albums on the X5ii, and can get to an albun within a matter of seconds using this method.

      This is a really thorough review – thanks for taking the time to do it, Brooko, and thanks for sharing the nice hi-res pictures!

      I would like some advice. I’ve only used ipods as DAP’s and am ready to either amp it (as I’ve got HE-400’s that sound pretty weak with just the DAP) or buy a separate DAP that I would use for everything but gym listening.

      I’m looking for a portable solution that I’ll use primarily at home when I want a relaxing listening session. The only headphone amp/DAC I’ve had experience with is the Meridian Explorer, which provides plenty of power to the HE’s. I’d like to find a similar experience using a DAP as a source.

      Would you suggest a new DAP? Amping the iTouch? Thoughts?

      • Reply June 15, 2015

        I would suggest CLAS SOLO and Duet amp if you like using the ipod/pad

        Thanks. I know there are plenty of Apple nay-sayers out there, but I’ve always rated the later i-Devices pretty highly as far as sonics go. They’re just limited on expandable storage space and power – which is where the Fiios excel. Hard to go past the Apple UI though.

        I guess it depends on what you’re looking for, and what features you value. I personally haven’t heard a lot of the “increased dynamics / bigger sound stage etc” that a lot of reviewers talk about when adding amplification. To me – an amp changes 3 main (useful) things : impedance (useful if you have a higher impedance source and sensitive earphones), hardware EQ controls (eg bass boost), and most importantly and increase in clean and constant power (voltage & current). If your headphones need more current or voltage than your DAP can supply – which I’m guessing you need with the HE-400s, then that is where the amp will be necessary.

        For a nice portable solution – I always really liked the Headstage Arrow series, but if you’re going to be spending $300 on an amp, then it may be better to just look at something like the X5ii (and no amp) because you will get argaubly better SQ and features. For a cheaper solution – even the Fiio E11K supplies very good clean power.

        I’m not sure if Lieven has the HE400, or access to one? If he does, maybe he can try it with the X5ii, and tell you what he thinks.

          My iPhone 6-plus sounds better than my iPhone 5 and iPod Touches. But adding the Oppo HA-2 gains me very little over the phone alone, and my older Verza isn’t as good as the HA-2. If someone asked me, I’d say get a much better amp, or skip that and get the DAP.

        Thanks. It’s a step-up from X5 original, but its incremental rather than exponential, or evolution rather than revolution. The X5ii (IMO) still represents extremely good value for money – especially compared to some of the other boutique offerings.

          I think unless you absolutely need to have the X52G or you never owned the 1G, then perhaps you could give it a miss. Unless $350 is no skin off your nose.

              OK.
              I have owned several DACs in the FiiO range and have absolutely no issues with any of them. Except perhaps earlier models had a bit of background hiss.
              My reference headphones are the Shure SE846CLs. Even my Oppo PM-3s don’t come close. But different strokes…

              I also purchased the Oppo HA-2, but to me, the FiiO E12A sounds better when paired with the FiiO X5. But all I am commenting on are my own personal preferences and opinions.

              Your taste in music may vary vastly from mine.

              I am a Jean-Michel Jarre, Andreas Vollenweider, Darshan Ambient, Tangerine Dream, Art of Noise, Jimmy Smith, Eric Gale, Herb Alpert, Barry White, Herbert von Karajan (with Berlin Philharmonic Orchestra), Beethoven kind of person.

              The review is well written and if I can get a buyer for my X51G, I will go for the 2G, but for now, I can play DSD256 with an iPhone 6 and HA-2 quite happily paired with my Shures.

              Just my opinion sir.

          I have a choice (both new to me) of the Blue Mofi with the built in amp or the B&O H6. I’ve read up on both so hoping at least one of these matches well with a new DAP (leaning towards an X5II purchase).

                        I got the Brooklyn Tree (GH1) woodie recently. A little darker, more mellow than the 325e, but more uneven in the treble. Unless it flattens out some after the 150 hours already played.

                        I thought about trying the RS2 and seeing if that was closer to the 325 than the RS1 was. I think if I ever end up getting another Grado, it’ll be RS2 or 325 again.

                Actually – the reviewer (me) points out good points and bad, doesn’t mention prettiness or sound stage (IMO with DAPS, the headphone has more influence on the soundstage than the DAP does), and actually says that its an incremental rather than exponential upgrade. I’d love to be able to review the AK Junior against it – but unfortunately I don’t have one, and at this stage no interested in buying one just for a single review/comparison.

        The Momentums aren’t difficult to drive, and if you’re mainly using them on-the-go, I’d probably recommend staying with the X3ii. It’s cheaper, smaller form factor, and you’d be unlikely to kiss the lift in fidelity (particularly if most of your listening is portable). If on the other hand you plan to use the DAP also as a DAC, and as part of an integrated system, and if space (dual slots) is needed, then the X5ii has the upper hand. At the end of the day – I’d pick first on the feature set you need.

      How is the X5ii compared to the DX90?

      Reading on the train, so may have missed it but how does the sound compare to your Micro iDSD?

      Does it need to burn in to sound better? What is your take on it?

      Is it known if you can do more than the 128GB for each slot?

        I haven’t tested it myself but it should be ok. The guys on Headfi also know more about it

      I have X3 2nd gen. Is it a wise idea to upgrade to X5 2nd gen or is it worth the upgrade. If the difference is too little I would like to be satisfied with my X3. Kindly suggest

        wanna ask the same thing. planning to get an x3ii if the x5ii is not really a big step up for IEMs which aren’t power hungry.

      sorry, but it would be nice if you can answer just a question, i have a X1 1st generation on may way and I have a Senheiser Amperior, Now i have the chance of getting a cheap (in my country these gadgests cost more than twice) X5 2d generation.

      So my cuestion is : Do you think i would get a noticeable difference between the X1 and the X5II?

        Of course there’s a huge difference. That’s logic.

      I am very new to the DAP world so please forgive my ignorance. I’ve been doing a lot of reading but still can’t seem to get the answer to my question, and you folks combine the technical skill with the real-world knowledge I look for in a reviewer.
      So, here’s my question: I recently ripped my modest collection of CD’s to FLAC using DBPoweramp (great tool by the way) and I have a little over 115GB of content I’d like to play on my tried & true (read ‘old’) receiver/amp and tower speakers. Are the Fiio DAP’s (X5iii and X3ii) a good answer for this, or should I be looking at a different solution? Portability is not that important to me, but getting good sound quality out of my music is.

        You can always find something that’s better, but try to maximize what you have first. Impedance matching, amount of gain, fine tuning for the gear and the room are all factors you should address.
