3 ultra-mobile media players

Three new players for our product survey. The "featherweight" tests.

Today's three players certainly won't weigh you down or be awkward to carry. The heaviest among them weighs only 38 grams and is no larger than an iPod Nano. There's even one you wear round your neck as a necklace!

For those of you who like a light-weight product, these are for you: we’ve got the Cowon iAudio U5, the Dane-Elec Music and the Sandisk Sansa Clip
