Cool Sleep Earphones
I recently bought these http://www.sleepphones.com and am enjoying them every night while sleeping in motels with street noise, a snoring friend, and inadequate window curtains. Its more comfortable than small earphones and a sleep mask. I'm able to pull the band down over my eyes and ears. It blocks most of the light, not quite as good as a real sleep mask but easier to just have the one device. It does slip off my head or down my neck or rotated so the speakers aren't over my ears sometime during the night.
I've been trying a random delta binural beat looped and the Delta Sleep System by Dr. Jeffrey Thompson. Any recommendations for alternative audios would be welcomed.
