Excerpt: My regular Bose noise canceling headphones were four years old and still like new because they were hardly used. I thought i'd lost them, so ordered the new Quiet Comfort 15 Acoustic phones. THEN, my 'old' 'phones were found, so I can directly compare the sound production between 'old' and 'new!' I have a hearing loss, therefore good sound and cancellation of environmental background noise is important.
Excerpt: These are wonderful headphones. Very comfortable and block out so much unwanted noise. I use them while riding the subway to and from work every day. I can actually hear my music over all the train noise! I would definitely recommend them to friends.
