The musicians plugs I have sit pretty close to flush with my ear so you would like be able to sleep with them better than off the shelf stuff. I’d recommend going to an audiologist and inquiring about this scenario.
Thank you! Looking more closely the sensaphonics website has sleep earplugs additionally. From what I see the db reduction and profile are same, but the more expensive ones do more to even out the reduction across the audible range for better quality I guess. I am going to check with the audiologist in my area their site recommended tomorrow to see about getting ear molds taken.
