What customers say about "Key Specs"
Fiio X5-II (2nd Generation) High Resolution Music Player (Black)
  • Love how smooth the interface is, the display is clear, crisp, and easy to read.
  • The screen has nice color reproduction, good for those of you that love album art.
  • The large artwork screen.
  • The menus are sharp on the display.
  • The slight delay between displaying the artist list and the albums is shorter if you have a huge selection, thus saving on battery life a bit.
  • The display is small and uses a tiny font.
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

What customers say about "Size & Weight"
Fiio X5-II (2nd Generation) High Resolution Music Player (Black)
  • The build seems to be quality and I like the size/ weight.
  • Nothing compares to the quality of sound that comes out of this little machine, for its size and price.
  • It looks very similar to an iPod, to be honest, and the weight and size are also comparable.
  • it's beautiful, like all the other Fiio products I own. It's smaller and lighter than the Gen I, you can actually carry in jeans pocket.
  • I felt as if it were sturdy by the weight of it.
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.

What customers say about "Features"
Fiio X5-II (2nd Generation) High Resolution Music Player (Black)
  • A nice feature between the two memory cards is you can create on-the go playlists that combine data from both cards.
  • The use of removable memory cards that can be directly managed is very convenient, since I personally do not like to have to use software like iTunes to manage my files.
  • My favorite thing though is simply the versatility of file formats you can use, you aren't limited to the usual formats but you can use the FLAC format.
  • I like that this fiio device has 2 sd card slots cause I have loads of metal music in my collection and need extra storage space for it but I was hoping for better battery life it's not terrible but doesn't seem to be great either!
  • Difficult to use: The menus are very slow once you get into the 100 GB range. If you're using the "Categories" section, expect 15-30 seconds delays after choosing an option. To speed things up, I use the folders section since I already organized my folders by artist/album.
  • Great but it does take getting used to , some controls are a bit odd but over all great expandability and sound.
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.

What customers say about "Power"
Fiio X5-II (2nd Generation) High Resolution Music Player (Black)
  • Plenty of space availability, and the battery life is great!
  • It takes three hours to charge and I clocked battery life at approximately eleven hours.
  • The battery life is specified at 10+ hours, which is conservative as I get 11 to 12 hours from its 3300 mAh battery, more if I'm using the Line output which powers off the headphone amp.
  • Terrible battery life, cumbersome to browse through files.
  • No indicator which says battery is fully charged.
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.
