Pros: I tryed a lot of disks and I like thes the best and there cheap. Burned 100 of these and not one single problem. I'm going to stay with these.

Cons: none

Pros: Looks

Cons: DRM, can't use without itunes, no fm tuner, can't drag and drop, small screen for size of unit, converts music and video to unusable format,to many to name.

Overall Review: After being turned on by the looks of the ipod I quickly found out that was the only good thing about it. You need to have itunes on your pc just to be able to use the thing..can't drag and drop directly into ipod..everything has to go through itunes which converts the original video and audio to an unusable format...your avi files will be converted so that you will not be able to put them from the ipod to another mp3 player, this is crazy being there's so many players that do not covert but play the original file. No FM tuner on a device this big is ridiculous.Please don't be fooled just because everybody else has one..I realized why buy what everyone else has why not buy something better.

Pros: Build quality, beautiful. Worked with mini ITX motherboard and mini ITX case. Lowered temps 10 degrees below stock intel heatsink.

Cons: None

Overall Review: Motherboard: ASRock Z87E-ITX LGA 1150 Intel Z87 Case: LIAN LI PC-Q03B

Pros: Best sound quality on the market..Build quality, fm tuner, voice recorder, awesome video quality, dictionary, text viewer, sound customization, Output power, much more...

Cons: People with ipods at the gym keep staring at it thinking "What the heck is that"..:)

Overall Review: Cowon makes the best sounding mp3 players and pmp's on the market...nothing better out there...once you own one your will never buy another brand...they are that awesome...best of all no need to use software to load music..just simple drag and drop directly into the unit...shows as a drive in "My Computer".

Pros: build quality

Cons: Horrible sound, course and glaring high's and mids,can't listen for long periods..no bass.

Overall Review: These were one of the worst IEM's I've tried..second worst I've owned..just another one added to my collection of un-used IEM's.
