Several foam earplugs in the results list an NRR of 32 dB.
Most listings describe the earplugs as foam or another very soft material; several specifically call them “super soft foam.”
Descriptions list uses such as studying, sleeping, concerts, travel, racetrack/races, playing an instrument, riding a motorcycle, and working around the house.
One listing explicitly includes “Washing and Reusing” among its features; another notes long-term use and that some earplugs come with a case.
Some packages include a storage box or a carrying case.
Listings repeatedly describe them as “super soft” or made of very soft material and note comfortable casings suitable for long-term use.
