The Nano's included Apple earbud headphones are better than what its competitors typically bundle; and audio sounded pleasing using the earbuds. In PC World Test Center evaluations, its sound quality was impressive. Our test equipment measured a very high signal-to-noise ratio, meaning that the player introduces little hum or hiss into the audio. The Nano's overall performance score ranked third among currently tested flash-based music players.
Not surprisingly, given Apple's consistent approach to all of its music players, the Nano continues to lack features that are common on competing flash media players, including a built-in microphone for voice recordings and an FM tuner. To make recordings, you'll need an optional accessory that provides a line-in jack. The optional $49 iPod Radio Remote adds FM capability.
Like its predecessor, the Nano's headphone jack is on the bottom of the unit, next to the standard iPod dock connector. This means the device is best placed in your pocket upside-down, to avoid putting strain on the headphone connector.
The Nano includes a USB cable to charge the player via your computer. Apple rates the Nano's battery life at 24 hours for audio (up from 14 for the previous generation), and 5 hours for video.
What the Nano lacks in a few features and flexibility, though, it makes up for with its stylish flair. With the Nano, Apple delivers a highly capable, eye-catching media player, including great audio quality and a bright, high-resolution display for watching video.
