Fiio X7 MP4 32 GB titanium – MP3 Player

The buttons and touch screen are great to use..very responsive and everything you might want to adjust is there
Touchscreen is great as is the Fiio music app
The native music player and the overall operation is very fast, reacts instantly to every input.
The UI is fairly idiotproof and the touchscreen works well.
Unlike most portable players, this unit offers a full (apx. 2” x 4”) touch screen display. The display has adequate resolution (233 ppi in 16.7 million colors)

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.
