Sony's new NWZ-E450 entry-level Walkman may look rather ordinary on the outside, but it's got something unique wrapped underneath -- karaoke mode. Here's how it works: not only can you throw in .lrc files to get auto-scrolling lyrics for your songs, but the device can also automagically reduce the lead vocals and let you be the rock star. Of course, the latter feature may not work as well with your occasional dose of Slipknot, but as you can see in our hands-on video after the break, Leona Lewis' gorgeous voice is good to go. The rest of the spec sheet doesn't look too bad either: MP3 / WMA / AAC / MP4 / WMV playback, up to 50 hours of music battery juice, 2-inch QVGA LCD, voice recorder, FM radio, 4GB to 16GB of memory, and it comes in black, red, blue, pink and green. Available in August starting from £70 ($108).
