PC World have published their review on sound-quality tests of some major brand name portable multimedia players available to consumers. 'The latest generation of portable audio players offer interesting new features and more storage, and the best of them deliver excellent sound quality. The highest-capacity player we've tested recently is the 80GB Apple iPod, which can store around 20,000 popular songs of average length and compression level. The Microsoft Zune has a neat new wireless sharing feature, and the SanDisk Sansa e260R integrates easily with the Real Rhapsody online music service. Many models appear similar at first glance. We point out differences in features and performance to help you weigh which is the right player for you.'
