Hi, my partner is really struggling with lack of sleep due to neighbour noise, and he is super stressed and worried it's going to affect an ongoing health issue. It's twin toddlers next door so it's not like blaring music, we can't ask them to 'turn them down'! They've just moved in so it's a new issue. He can't use ear plugs due to a problem with impacted wax in one ear (lovely, sorry). I wondered if there was such a thing as ear defenders that you can comfortably sleep in, ie not those big bulky ones? I've searched online but can only find earphones designed to sleep in, which you can play music through, rather than simply noise cancelling ones. Any ideas??
