What customers say about "Size & Weight"
 
Fiio X7 MP4 32 GB titanium – MP3 Player
  • Would I reccomend it? Yes because the sound quality and the build quality are great.
  • The player itself is very well made and feels solid
  • Build quality is top notch, its very heavy, almost like if it was a solid block of aluminium
  • Fantastic build quality, and customizable with different amp modules.
  • It feels like a million dollars straight from the box. The x7 is a fairly hefty device and is quite weighty too.

What customers say about "Features"
 
Fiio X7 MP4 32 GB titanium – MP3 Player
  • great bit of kit ...revisiting my love of prog rock ..only this time in flac format..
  • Even with the standard AM1 amp module it sounds excellent.
  • Loading music wasn't a problem as I inserted the micro sd card from my old Fiio X3 and it read the files and album art perfectly.
  • The sound quality is amazing, I'm no audiophile but I know what sounds good and doesn't. The X7 offers real depth of sound
  • The stock am1 amp module is meant for in ear monitors but with it set to high gain it drives my oppo pm-3 headphones with the volume at between 65% to 75% on average.
  • Sounds great, but it lacks the punchiness that other music players deliver with a Hi-Fi DAC.

What customers say about "Power"
 
Fiio X7 MP4 32 GB titanium – MP3 Player
  • Battery life as advertised which is not great but it's the same as others
  • The fully charged battery lasted approximately 8.5 h while playing the AKG K701 at a moderate listening level (volume setting = 66) on high gain in Pure Music Mode.
  • Great battery life when in pure music mode. Can play tunes all day long before I have to charge it.
  • Great sound quality, much better than iphone user interaction is great, 10 hours battery life
  • Two problems with this dap: weight and lack of aptx. Battery life is also a little short at around 8 hours.
  • I found out that the battery when fully charged lasts only 5 hours and half. I've charged it before leaving on a 6 hours trip.
