I'd really love anything more effective than foam earplugs for sleeping (esp. something that can block or cancel bass and thumps propagating through the walls/floor/ceiling) while still being portable. I tried the QuietOn Sleep, but they didn't seem any better than foam earplugs (and possibly a scam - i.e. lacking any ANC at all). Anyone knows about any such things?
