Damn It

My headphones aren't working. Well, one of them is, but the other requires precise jiggling and holding to work. I have the $10 in-the-ear, thin headband Sony headphones that I've pretty much always bought, but I'm tempted to upgrade. My dad has a pair of thick cuff headphones, also by Sony, that he likes, and my sister Drew has got ear-plug style headphones by Sony that have some sort of rubbery cuff that expands to fit the ear and actually stayed in when I played with them. The ones my Dad has are $30, my sister's are $40. Is it worth it? I need to purchase these before I fly to San Fran--no food on my flight and no music will make me a very unhappy camper.
