Hi Sarai, While I do not know of any noise canceling headphones that will fit in your BrailleNote case, I do know of, and use a pair of Senheiser noise canceling headphones. I do not know what the model number is, however you can find them at Best Buy, Circuit City or any electronic store. They come with a black pouch for storing the headphones and you can also store other accessories in the pouch as well. They are very light, compact and sound great!
HTH, Julia
