Our Verdict If you want great sound from a large portable library tunes, this X7 will do just the job For Great sound from all file types easy to use bass weight Against Screen lacks some detail and resolution Reviewed on 26th January 2011 The Cowon X7 is looking to challenge the iPod Classic as a roomy source for media. A 120GB hard disk drive (and 2GB of flash), large, PDA-style screen, and exhaustive features and format support are its key selling points. It also has an FM radio, sound recorder and image viewer, plus Bluetooth support, a huge battery life and an AMOLED touchscreen. There's no multitouch – but regardless moving around the clear interface is painless. Loading tunes is a simple drag-and-drop affair. With plenty of room for high-quality AIFF, FLAC and WAV files – AACs and MP3s work, too – the X7 delivers a balanced and open sound. There's no hint of hardness and plenty of weight to bass. More after the break The 480 x 272 resolution 4.3in screen reneges slightly on its side of the bargain, with video (AVI, WMV and DivX among others) looking fine but lacking detail and resolution compared to the best. Despite all the features, the Cowon is a simple proposition: a big hard disk and great sound from any file type. Works for us.
