Review title: They hiss and are tight.
Product review: I really like the sound quality of these earphones, however, when noise canceling is on, there is an audible hiss. The hiss is almost more annoying than the noise. I haven't used these on an airplane, just in an office with a refrigerator, fluorescent lights and a lot of computers. Also, these start to hurt my ears after about half an hour because they are tight.
