Summary: The Cowon O2 isn't flashy, but it's an incredible value for a convenient way to take your video library on the go without the hassle of converting files.
Pros: The Cowon O2 is an affordable and powerful portable media player with outstanding audio and video format support, a large touch-screen display, impressive battery life, and SDHC memory expansion.
Cons: Screen resolution is disappointing on the Cowon O2; menus lack ID3 tag sorting; DRM-protected WMA and WMV formats won't play; videos must be bookmarked manually; there's no FM radio; no video recording; and the player's all-plastic construction is thicker than we'd like.
Excerpt: Sure we have plenty of complaints about Cowon O2 mainly dealing with the user interface , but in the end is still a respectable PMP with the signature warm sound typical to Cowon. The O2 is too big to fit in your pocket which makes it a good candidate for a protective case since its likely to tossed into a bag or carried by itself. If you have read any of our case reviews you know that we are fans of the Noreve cases. This one is no different.
Conclusion: A few more features like Wi-Fi would have been welcome, but we still love using the Cowon O2 - with the ability to play back almost any video format without conversion proving a crucial time saver. Not sure naming it after a telephone network's a good idea though.
Pros: The 4.3-inch widescreen touchscreen is responsive, big and beautiful. Flash, meanwhile, not only saved everyone of us, but with vast amounts of Flash memory onboard (Up to 32GB), it means you can store entire DVD box sets onboard the O2 while keeping battery drain to a minimum. Best of all though is the sheer number of codecs supported: you could make up a file format and it'd play it. Probably.
Cons: Compared to a svelte iPod Touch, it's a clunky brick of a PMP: at nearly 2cm thick it's almost too big to hold if you're forced to stand on the train. While we like the ability to browse your tunes with video running in the background, the music library does look cheap. Cowon could learn a thing or two from Apple, as a slicker interface on such a lovely big screen would go down a treat.
Excerpt: The previous model that Cowon launched in India was the A3 PMP that fared rather well in our tests. The Korean company’s latest offering in the Portable Media Player segment is the touch screen O2 and here’s how it fared. Form Factor The O2 is a little on the heavy side at about 205g so toting it around in your pocket is not really an option. To elaborate further, its dimensions are – 119.5(W) x 73.4(H) x 18.0(T) mm.
Conclusion: What can I say? Yes, the O2 plays videos, there’s not much to complain about. It doesn’t play ever format as advertised, and it doesn’t give me the BBE sound enhancements I’m used to from Cowon – but it plays most videos well, except certain 720p HD, MKV, and/or h.264 material. The interface is clumsy, lacks refinement and usability.
Pros: Plays lots of video formats without converting, good subtitle support, Plays almost every audio format known to man, Good sound quality and BBE enhancements (for audio only), Ingenious “recent files” list, File/folder browsing, UMS/MSC mass storage class, works on any operating system, Flash memory (no fragile hard disk), SDHC expansion slot, Solid build quality
Cons: Not enough hardware buttons, Needlessly complicated, unintuitive, flawed, ugly interface, Sometimes laggy and sluggish operation, unresponsive touch screen, No EQ or BBE/M3B enhancements in video mode, Clicks and huge gaps between audio tracks, 720p HD and MKV/h.264 support has lots of issues, Lowly 480×272 screen instead of today’s 800×480 standard, No ID3 browsing, no playlists, No SD card integration, USB charging and USB connection with SD card are seriously flawed
Summary: Though it may not have internet browsing capabilities or much in the way of advanced features, the Cowon O2 is a solid portable media player. Thanks to its support for a wide range of file types, you'll spend less time trying to convert videos from one format to another and more time actually watching them.
Conclusion: The O2 is a very good digital media player , but it won’t meet everyone’s needs. It delivers fantastic sound, but it’s totally inappropriate for someone with a Rhapsody or Napster “to go” plan, for instance. And while it has a fabulous display, this 8GB model might not have enough room for more than a couple of films (although that SDHC slot is a welcome feature).
Pros: Supports several photo, music, and video formats; exceptional audio and video quality
Cons: Chunky form factor; no Wi-Fi support; doesn't support VOB and QuickTime files; can't play encrypted audio or video tracks
Summary: Though its touch interface doesn't match that of the iPod touch, the $219 Cowon O2 is a good choice for those who want a bigger display, broader format support, and expandable memory--but find the Archos 5 too large and expensive. The inability to sort tunes by ID3 tag info is a bummer, but overall the O2 is a solid pick for the price.
Pros: Large touchscreen display, Supports most A/V formats, Good sound enhancements, SD/SDHC Card slot
Cons: Music not sorted by ID3 tags, No DRM support, Lacks Wi-Fi, TV-out cable costs extra
