Enjoy the game from the 50-yard-line, block out your snoring spouse, or enjoy your new book in solitude. With NRR 33 being the highest grade for foam ear plugs, these noise-cancelling HEAROS Ear Plugs combine superior comfort and protection for your hearing. HEAROS Ear Plugs are made using stringent manufacturing processes for your peace of mind. Carry them with confidence in your car, gear bag or even in your pocket, so you can protect your hearing health wherever you go.
