IPod shuffle (2nd generation)

The 2nd-generation iPod Shuffle was announced on September 12, 2006 by Apple, which called it "the most wearable iPod ever". First shipments of the unit were slated for an October 2006 arrival, but actually started shipping on Friday, November 3, 2006. The second generation initially featured a lone 1 GB model in a silver brushed aluminum case, similar to the 2nd-generation iPod nano and the older iPod mini.

Features
The new model was less than half the size of the 1st-generation model at 41.2 x 27.3 x 10.5 mm (1.62 x 1.07 x 0.41 in), and was the size of the iPod Radio Remote. Apple claimed it was the "world's smallest MP3 player". This generation included the new built-in belt clip, and the actual unit itself was thinner, with the entire device weighing only 15.5 g (0.55 ounces). The power/shuffle/no shuffle switch from the first-generation version was separated into two controls to avoid an accidentally selected mode of operation. The formatting of the iPod itself was new to Apple, as the second-generation shuffle only formatted itself to.

On the 2nd-generation iPod shuffle, USB connectivity is provided via an included iPod shuffle Dock which acts as a for the transfer of data and the recharging of the iPod's internal battery through its headphone jack. The second-generation iPod shuffle was also able to act as a flash drive, just like the first-generation iPod shuffle. However, unlike the first-generation iPod shuffle, the second generation did not have a built-in USB connector. This means that the docking station was required for connection to a computer.

The 2nd-generation shuffle could play MP3, MP3, AAC, , Audible (formats 2, 3 and 4), WAV and AIFF. Due to its low processing power, the only iTunes-supported file format that the iPod did not support is Apple Lossless.
