5.5G iPod

The 5G iPod was revised on 2006.09.21 with a brighter display, nearly twice as long video playback, search, and redesigned earbuds. It was the first model an 80 GB option. Commonly known as the 5.5G iPod, this model looks identical to the first revision.

5G iPodApple also trimmed $50 from the price of the 30 GB iPod, and the new 80 GB version sold for $50 less than the previous 60 GB 5G iPod.

And just as with the two previous iPod versions, there was also a U2 Special Edition of the 5.5G iPod.

Unlike competing devices that used MP3 file compression, the iPod with iTunes was designed to use the superior AAC (Advanced Audio Coding) audio format in addition to MP3. AAC generally provides superior sound quality over MP3 at the same bit rate, especially at 96 kbps and lower sampling rates, as well as more efficient encoding, which means smaller files.
