So, the Digital Power Station Plug-In for iTunes is launched. It's extremely powerful and customizable in its ability to have many different profiles for speakers and headphones as well as separate variations for music and movies. It already contains a wealth of profiles for the speakers built into the various models of Mac computers as well as Universals for different headphones, speakers, and earbuds, and even some profiles for specific devices, but I'm curious.... what kinds of third party speakers and headphones are you all using? Do you use different listening devices for different situations? Do you have a pair of "studio-grade" headphones or do you rock out on your iPod earbuds? Maybe you went out and purchased a pair of earbuds with a color scheme to be a cool fashion accessory as well as a listening device. How many of you have noise-canceling headphones? The more we know about your individual needs, the better we can customize and optimize your experience.
