SRS Labs has just released MyTunes, a free iPhone app that rather dramatically enhances music playback on your iDevices. Instead of using the stock player provided by Apple, you launch the MyTunes app, select your playlists, albums or artists, and you're away. The sound of most tracks transforms in an often spectacular fashion. The basic app is free. It takes a little effort to explore all the features provided, but if you try it, it may well end up having a permanent place on your iPhone or iPod touch. The app also will work on an iPad, but MyTunes is not universal, and a separate iPad app is coming later this year.
