I have been using these headphones for the past 8 years as I have a tendency to fall asleep listing to my mp3...currently a Zune. These are the flattest most comfortable headphones for this purpose.......much more reasonable than specialty items.....I also toss and turn and like the fact that they disengage on their own.......wrap arounds would not work for me. I have tinnitus and cannot use earbuds, which if you turn the wrong way........get imbedded in your ear canal.Downside..............this activity eventually will destroy the cabling at the connection to the headset. Current phones have lasted almost 9 months...I am hoping there was a prod mod to improve the termination. PS: They did fix it. I have been using the current set for 1 1/4 and they are still going strong. Hurray for PhilipsPlease do not ever take these out of production
