following, as I just recently bought an E09W it's superb to be honest!
not 100% keen on the look of it, but the sound out the speakers is amazing, the beats and styles are amazing too for the cost. I do think the E09W looks far better visually than the BK3 (the E09W looks more expensive)
it's lightweight, but I'm disappointed no USB drive for midi files is possible. or SD card slot etc.
wondering what other options I may have either that I may get for my phone a midi file player.
