My lovely wife, who I love dearly (!) has the most guttural seismic snore ever to erupt from a human being. To sleep within a kilometer I need to wear some type of noise abatement device. Other than modification of industrial earmuffs, my new set of CIEM's have been the best thing I've found to get past the feeling of trying to sleep with my head resting in a jet engine. Enclosed Over-the-Ear headphone are akin to wearing a motorcycle helmet let alone risking cable strangulation, standard universal earbud-types seldom stayed put over the course of a night's sleep, I tried some small ETY-type flanged and was always afraid I'd wake up with a cable hanging out of my ear and the the earpiece hanging out of my mouth. CIEM's aren't perfect but they are relatively comfortable and relatively safe.
Sweet dreams.
