Works well. Comfortable. I use them over a pair of in the ear earphones when I go the gym. I listen to audible.com books. The problem is, my favorite gym has music cranking and I would rather not damage my hearing trying to drown out the music and listen to my spoken word recordings. This solution has proven superior to using an over the ear headset. Therefore I have them all on for a period of two hours three times a week. I don't know if they would be comfortable for all-day use, but certainly for two hours at a time they are wonderful. Their degree of noise suppression is also very good.
