I am able to have my screen off and still stream Pandora, regardless if I have my headphones in or not. I am running the latest Energy ROM but I also use an EXT-USB to 3.5mm adpater w/built in mic. And audio quality thru my Shure Headphones is on par with the Android Hi-Bit Rate version. (Well atleast on my Touch Pro - when I run the much better looking Android App in XAndroid)
