PROTECHS Quiet Time Foam Ear Plugs deliver an NRR of 33 to significantly reduce noise for sleep, focus, travel, and loud environments—ideal for blocking snoring and steady background noise while still hearing important sounds like alarms. The cylindrical design fits securely in average-to-larger ear canals; proper insertion (roll tight, insert, hold 20–30 seconds) ensures an effective seal. Many users reuse pairs multiple times, making each pack last for months depending on hygiene preferences. Made in the USA.
