Hello, I'm looking for a pair of IEMs to help me sleep. I'm an extremely light sleeper and it's hard for me to go to sleep if I can hear ANYTHING. Note that sound quality is not a huge factor here, I will be essentially just be using them to play brown noise via the Simplynoise app on my iPhone. I'm not worried about treble too much, a mid-to-low focused product would probably work best. I'm trying to find something $50 or under so I can buy multiple pairs in case one breaks. Comfort is the primary factor. I want something I can literally wear all night and not have sore ears when I wake up. I've seen the Shure SE215s and Westone UM1s mentioned for comfort, but those are a bit out of my price range. I'd greatly appreciate any suggestions or info anyone could provide. Thanks!
