Product Comparison: Fiio X3-II vs Fiio X3-III

General Specifications
About the Product
The black X3 (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 X3-II utilizes a Cirrus Logic CS4398 DAC coupled to a finely tuned low-pass filter offering extremely low noise and phase distortion. Additionally, the tantalum capacitors in the analog circuit provide minimal internal resistance for the best uncolored sound. Dual crystal oscillators ensure the lowest jitter and highest precision playback of music at any sample rate, eliminating conversion artifacts.
Styled in black, the FiiO X3 Mark III is a high-resolution portable audio player with a host of ancillary functions and features. For instance, it can double as an asynchronous USB DAC capable of handling 192 kHz/24-bit PCM files. The player is also Bluetooth 4.1 enabled, though not at the expense of fidelity. Three separate PCBs have been utilized in the construction of this mobile player: one for the digital section, one for analog amplification, and another for Bluetooth.

What customers say about "Key Specs"
Fiio X3-II High Resolution Music Player (Black)
  • I also don't like the way it displays my files.
  • I love the way it shows me my screen art - as I've taken the time to tag and put in screen art for nearly all of my collection .
  • The font size is very small and hard to read. I ended up picking the theme with the best contrast so I could read the menus. Still, with less than good eyesight I can barely read the display.
  • The UI could be a bit more convenient and the display is not as great.
  • The display is fine indoors, but a little hard to read outdoors.
  • The screen isn't bright enough. And its small, so its almost impossible for me to read in daylight, forget while driving
Fiio X3-III High Resolution Music Player (3rd Generation)
  • I really like the Fiio, easy to use, perhaps not quiet as intuitive as the iPod but the benefits outweigh the negatives by miles.
  • Currently using a 128gb MicroSD along side it. I find the battery lasts me a day or 2 with normal use at work or gym. It does get warm while charging or putting lots of files on it, but not any warm levels to be worried about.
  • The sound is incredible, capacity is no issue, and now discovering high res audio is a whole new adventure! No hesitation in recommending, made the right (and a personally important) decision
  • The sound quality is excellent. It uses a micro USB connection which makes it very easy to charge with my phone charger and I have plenty of spare cables. It comes with two protective cases and screen protectors. Battery life is good and the bluetooth works okay.
  • Wonderful sound quality - and yes, even as someone who isn't an audiophile, I can clearly hear nuances in music that I missed before.

What customers say about "Size & Weight"
Fiio X3-II High Resolution Music Player (Black)
  • Small and compact for his pocket w/out dropping out or loosing it either.
  • It is very compact, but the sound quality is excellent.
  • All aluminum case, good size in the hand, screen is easy to read and back-lit.
  • The size of the unit is very nice for dropping in your pocket.
  • Minuses are a less than ideal interface and it is quite heavy for it's small size.
Fiio X3-III High Resolution Music Player (3rd Generation)
  • First, the size is perfect! It's slim and lightweight so if you are carrying around this and a phone, it's not a burden.
  • The X3 looks amazing, feels amazing in the hand and sounds amazing.
  • The build quality is excellent, it feels solid and a quality piece of kit.
  • It's a weighty big ugly LUMP, with little of the refinement of the IPOD.

What customers say about "Features"
Fiio X3-II High Resolution Music Player (Black)
  • You can have as much memory cards as you want, which makes your storage space virtually infinite.
  • You can use this as a beautiful sounding Hi res audio player with natural slightly warm neutral sound as well as a DAC to listen to your music on you computer with much better quality.
  • However, in addition to purchasing the MP3 player you have to purchase a memory card and a device to format the memory card.
  • User interface is horrible. Selecting genre, artist or album is very complicated.
  • Making internal playlists is borderline impossible, and importing playlists is very complicated.
  • Excellent player, a little tricky getting the software figured out, but when you do it is well worth it.
Fiio X3-III High Resolution Music Player (3rd Generation)
  • You can add larger cards, use different cards or replace damaged ones.
  • Very easy to get up and running, simply copy your i tunes music folder and paste it onto a memory card, ho hassles at all.
  • Bluetooth takes 15 seconds to initialize, it works without delay after this.
  • The user interface is truly awful and ruins the player for me personally. I'll give you some examples. If, like me you have a large and full SD card full of different music it is an absolute chore to scroll through the library.
  • The software is kind of difficult Togo around it and the Bluetooth does not work too good.

What customers say about "Power"
Fiio X3-II High Resolution Music Player (Black)
  • Battery life seems really good.
  • Battery life is acceptable.
  • Battery life is fine, more than four hours of continuous use.
  • I think that at this price point along with the size of this unit that the battery oughta' last longer.
  • With mediocre battery life. I'd say 6-8 hours that degrades to 6 hours after wearing it in for a few months.
Fiio X3-III High Resolution Music Player (3rd Generation)
  • Battery life!! I can not say how impressed I am with battery life of this device. I never feel rushed to charge it. I listen roughly 5 solid hours a day, low gain, volume ~30 on an iem and charge it once every two weeks.
  • I find the battery lasts me a day or 2 with normal use at work or gym. It does get warm while charging or putting lots of files on it, but not any warm levels to be worried about.
  • Battery life is good and the bluetooth works okay.
  • Battery doesn't last long. There are no belt-cases or similar on the market yet, so I cant use it at the gym unless stuffed in a pocket.
