Title: Noise canceling technology gives me headaches
Review: The sound quality is fabulous, however, the noise canceling technology in the headphones cause my ears to ache and also giving me a mild headache. I typically never get headaches, but after using these headphones over extended periods (hour plus) results in headaches and ear irratation, regardless of music genre or volume.
