Apple has unveiled the new redesigned iPod shuffle, which features both clickable “ring” buttons and Apple’s innovative VoiceOver technology, enabling you to easily navigate your favorite music and playlists without ever looking at their iPod shuffle. Available in silver, blue, green, orange and pink, the gadget provides over 15 hours of music playback on a single battery charge. The new iPod shuffle also supports Genius Mixes, the popular iTunes feature that automatically creates mixes from songs in a user’s music library that go great together. Genius Mixes provide the perfect way to rediscover music users already have, but may not have listened to recently. The fourth generation iPod shuffle will be available next week for a suggested price of $49 for the 2GB model.
