Pros: Moderate build quality, good file support, notable improvements over S9

Cons: Weak processor, does not use standard usb

Got this a while ago after a channel on my D2 died. Choose the J3 for obvious reasons battery life, file support, and since I had quite a good experience with my D2.


Listen mainly to trance, dnb, dubstep, jazz, classical

Using SE110, and sr80s

Firmware 1.20



- Battery life is one of its key selling points

- Speaker (improvement over S9)

- Expandable (improve over S9)

- AMOLED provides beautiful colours, and almost unlimited viewing angles

- Supports almost any file you throw at it be it audio or (most) videos

- Stock UI I find is better than S9, built into the J3 are 3 UIs which can be seamlessly switched between

- Hardware buttons! for pocket operation =]

- Flash support (limited to buttons however)




- Battery meter is useless, it shows approximations 100%, 75%, 50%, 25%, 0%

- Processor is a bit on a slow side, takes forever to process large images, and slightly more intensive flash applications

- Does not play most H264 videos, rmvb, mkv

- Battery life is rated at 62 hours, but steeply drops off with extended screen use, speaker use

- Build quality is not bad per se, but Cowon can try stepping up their media players with full metal bodies (J3 seems to have metal painted plastic for front bezel and some aluminium (dont even know if its real)

- Uses Korean phone 20pin for data, vid out, power
