My wife was getting sores on her ears from other headsets, so I purchased the Shure E2c for her. They work great. She wears them 8-10 hours a day without problem. Using the foam earplugs blocks out almost all noise as a bonus. She liked them so much a purchased a set for myself. She needs new foams and ear-wax guards about every two weeks (purchased seperatly as pack of 10).
