Pros: Quality Sound, Reverb, Surround Sound, plays Flac, BBE
Cons: Slow USB Speed, Slow charging(Approx 5 hours to recharge fully), Touchscreen responds wierdly at tiles
If you are in search for quality sound, reverb and loves flac, then here you go. The UI is decent and nice, I dont know why people give negative comments, the thing is that it takes two to three weeks to get going with the interface.
The audio enhancements have limitless enhancements, if you dont adjust it properly you may have scrambled audio. With proper adjustment of the several enhancements like mach3bass, 3d surround, stereo enhancement, reverb and a properly set EQ, you may have bliss.
Recommended in earphones
Sennheiser IE 8 Earphones
The only cons are
battery charging time (more than five hours) and low USB data transfer rate.
