I bought my wife noise cancelling ear plugs for sleeping because I (in her words) snore like a pig. She has several recordings to back that up. So I bought her these noise cancelling earplugs (Soundcore A20 in case anyone is interested) in the hopes it will allow her to sleep. I will eventually get surgery done for it, because I also have apnea. She hasn’t put them to the test yet because it’s not always that she can’t sleep, but I hope they will serve her well.
