my experience with noise reduce earphone be with the JVC hanc100 , which be a earlier , and fairly satisfactory headphone . I have be satisfy with it for about a year . this , the JVC hanc80 noise cancel headphone , be even better ! the sound rendition be superb . and this model have two mode of noise reduction : low frequency , and a wider range for more typical noisy environment , e.g. office , library , shopping , home -lrb- when relative visit -rrb- , auto travel , bus , aircraft , well , you get the picture ... I like the wide range . at home with airconditioner , fan , neigborhood sound , jet above , radio blare , dog bark etc , the effect be comforting . add some music from you ipod or radio earphone outlet and you find yourself in a -lrb- quiet -rrb- heaven , listen to a high quality of sound reproduction . I be impress with the sound quality , and I have use earphone of various type for many year . one must understand that these , or any , noise-reduction earphone be exactly that : they be not noise-cancelling ! silicone earplug be the best you can do in that regard . best noise reduction be in the very low frequency -lrb- make my Boston MBTA subway excursion bearable -rrb- . the excellent sound quality be icing on the cake . get real ! this be not star Trek , merely the 21st century . you do not need to spend $ 350 for that high price brand ! this be a excellent product . recommend . also look at the JVC harx300 non-noisecancelling phone . they go over the ear , be very reasonably price , have fantastic sound . not design to be easily transport -lrb- do not fold -rrb- . I love they - have three , in each place in my home where I like to listen to music or tv .  JVC Full-Size Headphones -lrb- Black -rrb-
