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. On the second-generation iPod Shuffle, USB connectivity is provided via an included piece of hardware which acts as a docking station 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 second-generation Shuffle could play MP3, MP3 VBR, AAC, Protected 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. On January 30, 2007, Apple announced the addition of four new colors to the iPod Shuffle line - pink, orange, green, and blue, in addition to the original silver color. The orange color was a first for the iPod franchise. They also now came with new redesigned headphones that were not included with the original silver model. The box was also changed to have gray text instead of the lime-green text. On September 5, 2007, Apple introduced four new colors, including a Product Red version. The new colors were turquoise, lavender, mint green, and Product Red, with the previous colors discontinued. On February 19, 2008, Apple introduced a 2 GB version of the iPod Shuffle, retailing for US$69 and available in all the same colours as the 1 GB model. At the Apple Let's Rock Event on September 9, 2008, Apple once again released four new colors for the iPod Shuffle: blue, green, pink, and red, replacing the colors that were released in September 2007. The new blue, green and pink variants of the iPod Shuffle reverted to shades that were similar to the colors that were released in January 2007. In June 2009, Avon offered a gold iPod Shuffle (second generation) for $29 when purchased in conjunction with two ANEW skin care products.
