I be sit here listen to my music as I type this review , with the noise-canceling feature turn on so that I can not hear my scream kid upstairs fight bedtime . : -rrb- that be not , however , why I buy they . we go on vacation 2-3 time a year and I be tire of crappy headphone that do not block out any of the outside plane noise , be not comfortable , didnt ' stay in my ear , etc. . while we have not travel since get these headphone , I think these be what I be look for . the sound be very good and they be pretty comfortable . I do not think I would be able to handle have they on for hour on end , but they be good for plane ride . we 'll be take they with we to Italy in two month , so that will definitely make up my mind completely on these .
