ilounge: sounds like a classic!
Apple iPod nano Fourth-Generation (8GB/16GB) | iLounge
The single biggest audio change to the iPod nano isn’t one that’s glaringly apparent, or even touted by Apple, but it’s there: the sound chip has changed. Months ago, long-time iPod audio chip supplier Wolfson Micro made clear—with minimal discretion—that its chips were not going to be included in either the upcoming iPod nano or iPod touch refreshes, which were then unknown. Lo and behold, the new devices arrived, and they sound like the 2007 iPod classic—they’re cleaner, with a nearly non-existent static noise floor that’s as well-suited to audiophile-grade earphones as free pack-ins. That’s really good news for those who hope to use their nanos with better headphones; the fourth-generation model is definitely the best-sounding iPod nano yet.
