What customers say about "Key Specs"
xDuoo X3 II 2nd Generation AK4490 Bluetooth Portable HD Lossless Music Player
  • I love the build and sound quality and features of this unit. Really. Also i like the display.
  • The screen quality is decent – certainly nothing special or to write home about, but it serves its purpose fine.
  • The screen is crisp and clear. It has a micro usb port for charging and transferring files.
  • I was pleasantly surprised at the great sound quality. Very clear and not colored at all.
  • The screen completely stoped working after 2 months. I didn't use it too much.
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"
xDuoo X3 II 2nd Generation AK4490 Bluetooth Portable HD Lossless Music Player
  • I wanted my music player to be smaller and different shape than my cell phone.
  • It is compact and very well constructed and I believe it will last a long time with proper care.
  • The player is generally good, the sound emphasis on the mid and high frequencies. Compact and very light.
  • You get fantastic sound in such a small player with fantastic battery life.
  • The build quality is great. Pretty small as well so no problems taking it pretty much anywhere.
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"
xDuoo X3 II 2nd Generation AK4490 Bluetooth Portable HD Lossless Music Player
  • Album art looks good, and all the menus are easy to read and interact with.
  • The equalizer is amazing. The battery life is fantastic. I love how my headphones sound.
  • It sounds great--with the right headphones. micro usb cord and basic software make it easy to work with.
  • I love the size, the improved interface, the micro usb port, and the fact that it has, so far, worked flawlessly.
  • It needs a UI update to really compete. It is not slow but outdated and boring. Needs more customization and just a cleaner look.
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.

  • Sound quality is its true strength, and with a superb battery life.
  • I can go a week without thinking about charging this player, unlike my cell phone.
  • Pretty good build and I love the battery life. Have no problems with UI and think sound is good with decent headphones.
  • An excellent player if you care about portability, sound quality, and battery life.
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.
