If the sound is enhanced with the iPods software's equalizer (EQ), some EQ settings — like R&B, Rock, Acoustic, and Bass Booster — can cause bass distortion too easily. The equalizer amplifies the digital audio level beyond the software's limit, causing distortion (clipping) on songs that have a bass drum or use a bassy instrument, even when the amplifier level is low.[citation needed] One possible workaround is to reduce the volume level of the songs by modifying the audio files.[citation needed] Exactly how all the pieces came together -- there were parts from at least a half-dozen companies in the original iPod -- is not something Apple talks about. But one clue can be found in the device itself. Under the Settings menu is a selection called Legal, and there you find not just Apple's copyright but also a note that ''portions'' of the device are copyrighted by something called PortalPlayer Inc.

Try to avoid frequent full discharges because this can cause strain on your iPod battery. There is no harm in charging a battery even if is not totally drained. Unless you are watching videos on your iPod, I usually reduce the brightness to about 40 percent when listening to mp3. The iPod Nano is very tiny. In fact, it’s about the size of a portable flash drive (those little memory sticks that people walk around with and plug into their laptops). The iPod Nano has all of the features of the iPod mini, with the real differences being size, storage capacity, and technical scalability.
