I just found a way to energize the MP3s on an iPod. I copied all of my iPod songs onto my hard drive and re-encoded the files with the DFX Audio Enhancement plugin at 192kbps. Now I can hear every detail in the music on my iPod. It makes even my MX400 Sennheiser in-ear headphones sound amazing. Tracks without the DFX plugin sound dull and boring. I also tried the Slic Sound add-on earpieces and they make my MX400s have an almost audiophile quality.
Editor’s Note: The DFX plugin is not available for iTunes, but supports most popular music management software on Windows like Musicmatch, Media Jukebox, WinAmp and more. DFX 6 is a free download with limited features, and DFX Enhanced is on sale for $19.99.
