Addressing an apparent issue with Apple's iPod equalizer, one user has discovered a combination of iPod tweaks that fully eliminates equalizer distortion. While the iPod is generally accepted as a well balanced audio device, its bass tones often leave users wishing for more. A "rolloff" in lower tones when using headphones ranging from 16 to 32 ohms has also been reported, and Apple's bundled earbuds unfortunately fall within this range, according to dapreview. The user reports that by utilizing a free open-source program called MP3Gain to reduce the volume of music files and enabling the iPod's "Bass Boost" preset, bassy songs play without distortion or clipping. iPod owners can increase the volume output of their devices by running a utility called euPod, which removes built-in volume caps on European and U.S. iPod models to compensate for the softer output volume after running MP3Gain.
