The second generation Shuffle is great, isn't it? It's compact, has great features, sounds good, is perfect for jogging, etc. In fact, when I got mine, my only complaint was the little adapter to sync and charge it to your USB port on your computer. Unless you already had a USB extension cable handy, your Shuffle had to hang precariously from a USB port.
That's why this USB cable from Apogee is the perfect accessory or replacement cable for your 2nd generation Shuffle. It's easier to find since it's bigger than a dime. Plus, it has the same features as your OEM adapter. It simultaneously charges and transfers data (syncs your music). And, since it's a cable, you can let your Shuffle lay where it wants, not just sticking out of a USB port.
