|Sure, the iPod Nano is an enjoyable flash DAP that does what it's supposed to do: play music and look thin. Really thin. It's not exactly perfect in some aspects, though - take the design's vulnerability to scratching, for instance. We didn't pay 200-250 bucks to have our slender little nano go to waste, did we?|
EPL Technology from Hong Kong agrees on that, and so they came up the Evere A373/374. These cases won't only protect the nano from getting all ugly and all, but they also double as Bluetooth dongles. This means you can use a wireless set of headphones in combination with the A373/374 (and headsets are being provided a-plenty by EPL too). The A373 also comes with a built-in FM radio.
Two problems, still - the built-in battery will only last for some 5 hours when using Bluetooth headphones and the actual case makes your once-slim nano look like it recently took first prize in a local Food Frenzy (102 x 45 x 19mm, up from 90 x 40 x 6,9mm - also more-or-less doubles the weight).
Not a bad idea, though - especially if you insist on using Bluetooth headphones in combination with a Nano. If I recall correctly, the rep said it would cost 130 bucks in combination with one of their headsets. More info on the company's products here
