Cowon D2 is great, easy to navigate through and great video and audio quality. It also supports lossless audio files like FLAC and OGG (which I will be getting my music into). Small, lightweight although a little heavier than it looks. It has many options and features including a regular and scientific calculater, auto shut off, sleep and wake up timers, etc. More in about a week when I get really used to it.
Sleek Audio SA6 smaller than they look online. Nice easy fitting, comfortable. Right out of the box great sound quality. Comes with carrying case, treble tips and bass ports for customization in each earpiece. More when I am sure the sound has set in (burn in).
So, after about an hour with them now, these are my first impressions and right now all I can say is
First impressions of Cowon D2 and Sleek Audio SA6
