How to Change Bitrate Settings for Transfer MP3 to iPod from iTunes?
Basically what I want is my high-quality music to stay high-quality on my iPod because im pretty sure iTunes changes the bitrate of each song it puts on the iPod. Cause I hear totally different sounds and effects for the same song on my iPod then on my computer. For example, My Chemical Romance’s song :I’m Not Okay, I can’t hear them say “I’m not Okay” during the second stanza or shout at the very beginning of the song. I can’t hear that on my comp. But on my iPod I hear it. I want good sound on my iPod cause the sopund sucks. Or it could be headphones? HELP
I got Bose Headphones they blur the sound as well.
