- Sound quality It supports 24bit/192Khz Flac files and plays really amazing.
- Video quality This devce has really good video and game performance.
- Ease of use The new android 4.1 is really easy to use for me. Better than my expectations from a walkman.
- Portability It has a perfect shape and weight.
- Battery life It lasts approx~20 hours with hi def flacs and ~30 hours with MP3 and AAC. Really amazing.
- Media support It plays what you throw in it. I only could not try DSF files..
- Capacity 32Gb is really enough for MP3 type compressed files but I recommend to buy 64 Gb F887 for Hi-Def Music Files.
