FiiO X5-II overview

  • 1Description

The titanium X5 (2nd Gen) from FiiO is a portable high-resolution audio player and USB DAC for audio enthusiasts. The unit features an audiophile-grade architecture and premium components capable of playing files up to 24-bit/192 kHz in a variety of formats including native DSD, WAV, WMA, ALAC, FLAC, APE, AIFF, and more.

The X5-II utilizes a Texas Instruments PCM1792A DAC coupled to an OPA1652 for great dynamic performance, while the FET inputs for I/V conversion offer extra-low distortion and noise. Additionally, two top-flight OPA1612 chips provide low pass filtering and voltage amplification for extra-low distortion and noise. The headphone output employs two BUF634U chips for current buffering, resulting in a sufficient drive current for a wide sound stage, high dynamics, and good bass power. Dual crystal oscillators ensure the lowest jitter and highest precision playback of music at any sample rate, eliminating conversion artifacts.

The player offers a standard 1/8" / 3.5mm headphone output and a separate line out/digital (coaxial) out via 1/8" / 3.5mm. The X5-II has no on-board memory, but uses two microSD card slots supporting up to 256GB total. The 3300mAh Li-polymer battery provides up to 10 hours of playback under normal conditions. The user interface offers five unique themes, while the classic scroll wheel and 2.4" HD IPS color display offers easy navigation. You can browse and play songs via folders, songs, albums, artists, genres, favorites, and playlists. The 10-band graphic EQ and the 120-step digital volume control allow for custom-tailored sound and levels.

The X5-II is 15% lighter and 12% smaller than the original X5. The chassis is made of aluminum alloy and features a high-reflectance, fine-grain faceplate. The X5-II ships with a 3' / 1m high-current micro-USB data/charging cable, an 1/8" / 3.5mm coaxial S/PDIF adapter, a clear case, three screen protectors (1 applied in-factory), an HDtracks coupon, and a set of three Bodywork stickers (USA flag, wood grain, and carbon fiber).

    FiiO X5-II reviews

    X5 (2nd Gen) Portable High-Resolution Audio Player (Titanium) is rated 4.2 out of 5 by 36.
    Rated 5 out of 5 by from No need to recreate digital music! Unlimited expansion! I got the X5 2nd Gen as an alternative to an iPod. I love the option to play Apple Lossless format files (no need to redo my digital library!). It understands the music file attributes and is able to organize music by artist, album, music type. Also it reads read directly through folders. I can replace the music by just changing the micro SD (no need to have a computer to re-sync). Simple interface. So simple that I feel that I'm missing something (guess I'm too used to have complicated visual interfaces), but I have everything I need. Only down: It feels slow when loading music, but once is loaded, it plays smoothly.

    Rated 5 out of 5 by from My music library, on me, all the time = awesome I've been an ipod classic person for forever, but the 180GB cap has been an issue. I am an audio engineer and I have a lot of music. My old ipod classic has finally died and are no longer made anymore so I looked for other options. I was very pleased to find the Fiio X5. The main things that I love about this product are up to 256 GB of music...that's incredible. Can import my old itunes library without having to go through and re-organize my entire library. Micro SD card storage (Drag and drop folder organization is way easy to use) I can store .wav files! (I store compressed files of my entire library, but as a music producer, there are times when uncompressed files are the only way to go) Line out feature (I can go into any studio, plug in my 'Samples' sd card, and have line level .wav files ready to go...super handy) The only bummer is that the operating system is pretty slow. It tends to lag when riffling through the menu (which is probably understandable being that it is accessing content on sd cards instead of an internal hard drive). Other than that, the X5 has been exactly what I was looking for, and then some. I think the price point was very fair and I would buy other Fiio products in the future.

    Rated 5 out of 5 by from Christmas is just around the corner The sound is strong with this Hi-Res player. It will make an MP3 sound 100x better. I was listening to David Bowie's 'Black Star' from HDtracks 24/96. The bass is strong without stepping on the mid range or high range. The same thing with Radiohead's 'A Moon Shaped Pool' HDtracks 24/48.

    Rated 4 out of 5 by from Fiio X5-II I bought this product to replace my Apple iPod with a FLAC/lossless-compatible portable media device. I listen to the Fiio X5-II through my stereo or paired with the Fiio E12A Mont Blanc portable headphone amplifier (itself paired with either Sennheiser HD 598 headphones or Sony MDR 7506 headphones). I found the Line Out port to be a very convenient means to connect to my home stereo. Overall, I am very satisfied with the Fiio X5-II. It sounds great, especially when paired with the E12A and a good pair of headphones or in-ear monitors (IEMs), and is exceptional for the price point. The Fiio X5-II is a sturdy, well-designed unit. I find that I prefer the feel of the clickwheel over the iPod's, as it physically moves, and provides nice tactile clicks it does. The layout of the buttons may take a minute to get used to, as the back button is to the upper right of the clickwheel, as a backspace or delete key would be on a keyboard. There are two ports on the top of the unit, the Line Out port and the Headphone Out port. Only their physical position distinguishes them, making it possible for one to accidentally plug a pair of headphones into the Line Out port, which is dangerous for the headphones and the ears of the users, especially those using sensitive headphones. The screen is clear with good color. I cannot speak to brightness as I always keep the backlight on its lowest setting, but even at that, I do not find it difficult to view the display except in bright sunlight. The user interface is this device's one fallback. It tends to get rather slow, making it difficult to quickly skip several songs in a row. At times, it can be slow to load a new menu; however, most of the time navigating the menu is not an issue. Although there is a method for browsing music by tag, I prefer to browse the music by directory tree. This was unfamiliar to me at first, but quickly became preferable. I used Fiio's recommendation and organized my music into separate folders for each artist, then created subfolders for each album. These are displayed alphabetically, so it is best to have albums listed by year of release first if it is desired that they be listed chronologically. I believe some of the issues that some customers may have had with the interface were fixed in more recent firmware release. I personally found the five display themes of the X5-II to be lacking, so I chose to use custom firmware that I located on the internet, created and provided by a third party. It is possible that some of the user-interface issues I have encountered are not present in the official firmware. The device does not have any internal storage, nor does it come with the microSD cards which are to be used with it. I concurrently purchased two 128 GB microSD class-10 cards for my unit. It is recommended by the manufacturer to use Class-6 or higher cards for best playback of lossless music, as slower cards may prevent the music from being read fast enough to be played. Music can be added via the USB port on the device or directly to the microSD cards themselves. Currently, 128 GB microSD cards are the largest supported; however, Fiio has hinted that larger sizes can or will be supported in the future. I am unsure whether or not this will require a firmware upgrade, but it should be noted that the theoretical limit for size of SDXC cards (the type supported by this player) is 2 TB, or eightfold the size of the largest current card available (with the exception of the 200 GB SanDisk microSD card which, at the writing of this review, was prohibitively expensive). Also, due to the microSD cards being easily removed, it is possible to rotate any number of them between the two slots, which I suppose may be analogous to having several mixtapes in the days of cassette decks, albeit tiny cassette tapes the size of a fingernail that can hold hundreds of hours of music. In this way, the storage of the Fiio X5-II is infinitely expandable, limited only to the number of microSD cards one possesses. In addition to the microSD cards, the Fiio X5-II can play music from a USB storage source, such as an external hard drive, via USB On-the-Go (OTG). I am unfamiliar with this technology, however, and have not used it. The Fiio X5-II can be used as an external DAC, a feature of which I am very fond. To use it, one must simply change a menu option from USB storage to DAC and connect the device to a USB port on a computer. On windows computers, one may have to download the official drivers from the Fiio website in order for this to work. I do not use a windows computer, so have had no experience with this, although it may prove difficult for the less computer literate user. For those unfamiliar with the concept of a DAC, or Digital-to-Analog converter, all digital sound has to be translated to an analog signal prior to being audible. In most computers, this is done by a sound card within the computer, and the signal is then amplified on the sound card and sent to speakers or to the headphone jack. In portable media players, the player's DAC converts the digital data into sound and passes it to an amplifier and headphone jack or directly to the Line Out jack. The DAC option on this device simply allows a user to use the X5-II's (presumably superior components and) DAC to play audio from sources outside of the player. I use this feature when listening to music and watching movies on a computer, as well as to play music from a computer through my home stereo. Notably, although the external DAC feature is very convenient, there are very good dedicated USB DACs on the market. Behringer is one brand which makes affordable USB DACs for those wishing to bypass their computer's soundcard.

    Rated 1 out of 5 by from Terrible (and terribly slow) interface If you're looking for a non-intuitive, frustratingly slow music player, then look no further. While it plays fine (and probably better than just fine), it is the least user-friendly, least reliable, buggiest piece of consumer tech I've encountered in quite some time. It's clearly not coming from the U.S. or an English-speaking development environment, and they have no idea what they are doing in terms of terminology, folder structure, etc. I wish I had returned this earlier... now it's past the time to do so. Save yourself money, frustration and all the rest. Stay away from this.

    Rated 5 out of 5 by from X5 GenII Initial Impression I picked up this unit a couple of weeks ago for a great price. The third gen is coming out so there will great deals on this unit. Of course the price will go way up the third gen beyond what I would spend on a player. Right now I'm taking it to the gym. I have been re-ripping cd's the have been sitting on a shelf for years, which is great. There are reports of the player being slow finding songs. Right now where I am with it, it is lightning fast, but I come from using Sandisks and Muvos. I currently have 1800 songs on 32 gigs of memory, which will take me some time to play all those songs. Not sure why someone would want to put 20,000 songs on the player other than being a DJ. A laptop just makes more sense for doing DJ work. One of the reviews likened using the player to a cassette, where the memory is thought of working like popping memory in and out of the player. Which doesn't sound too bad since I'm going through songs one by one. I'm resisting the temptation of hitting the skip button. That reminds me one thing that's kind of awkward is having to wake up the unit to change volume or skip a track - maybe there a setting to get around that. I downloaded some high def songs 24 bit. The file sizes are huge - 80 to 120 megabytes. You can hear things like the person taking a breath, bows hitting strings, the pedals on a piano. Great if your into that kind of detail. That's what compression takes out. The player has plenty of volume for my phones I'm running it about seventy. With exotic headphones maybe it would require an amplifier. So that's my summation at this point.

    Rated 4 out of 5 by from Extremely Nice I'm not a hard-core audiophile so if you are, take this review knowing it isn't written by someone who is. That said, this is an extremely capable and fantastic sounding player with a huge number of popular codecs supported. My primary reason for wanting a portable player was for well, it's portability - so that I could listen in the car, at home, or at work with minimal disruption. I love music, but audiobooks are also a significant portion of my listening time. One of the features that is very nice (but not perfect) is the resume play feature that allows me to turn the Fiio off and then resume where I left off when I power it back up. This feature (for me) is primarily for audio books. While this is nice, it is not ideal. A true bookmarking ability would be much better and allow me to listen to an audiobook, then listen to music and then resume my audiobook where I left off. I am aware that .m4b format on another line of players handles that need very well, but I have an intense distaste for needing to use an application to organize and sync my music/audiobooks, so that was not an option - which brings me to one of my favorite features of this player. it has an actual file system that allows me to keep my music/audiobook folder structure and browse it on the player. My audio is already organized on my computer by artist/author and I just have to copy that to the player and browse to the file to begin play. There is no need for wasting countless hours tagging, classifying, etc. in an application. The build quality of the player is very good and the user interface is simple and easy to use. The included silicone skin is a nice touch that has already kept me from damaging my player. The battery life is very good and charging is accomplished in a reasonable amount of time. If possible I would give this player 4.5 stars because the only real thing that isn't ideal is the lack of a true bookmarking feature for audiobooks.

    Rated 5 out of 5 by from A Dedicated Music Player for Studio Recording. I use this to sample and play back my studio recordings. It's a great device for high resolution studio tracks. Unlike studio monitors which are really flat, the X5 II has some sound enhancements that bring out a wide dynamic frequency range when paired up with some good headphones or ear monitors. Very clear and articulate sound, even at low volumes. The line out feature is great for the Car Audio auxiliary input. It has enough power to drive the Sennheiser HD280 Pro., and the Sure E2 ear monitors. But struggles to get loud with the AKG K240 Studio. On these headphones and ear monitors the X5 brings forward some sounds that are buried in the mix, and makes them clear. Battery life and charge time is decent. And the dual card slots are great for fast loading music. No proprietary software needed, and no need to go online to change up music. As for dislikes, I have none at the moment. Nevertheless, a great tool for studio engineers who want to sample their high resolution recording on something other than a studio monitor or smart phone. The sound resolution is great, and really brings out the best of what is recorded. And non-audiophile studio headphones/ear monitors work great with the X5 II. I'm glad I got this last version of Fiio's X5 series. The newer X5 III has a lot more smartphone tablet features. And that's good, but I prefer a dedicated high res player designed only for music playback.
