3M Disposable Earplugs Events & Concerts, 4 Pairs (8 Total Plugs), Noise Reduction Rating (NRR) 32 dB, Good Fit, Stays Put, Soft & Smooth Ear Plug Design, Easy To Insert & Remove (EPEC-4BC-SIOC)

Hands and earplugs should be clean before fitting. Roll plug slowly with thumb and fingers. Gradually increase pressure to compress plug into a very thin crease-free cylinder.

Insert compressed plug well into ear canal while pulling ear outward and upward with opposite hand.

Check fit after plug expands in ear. Touch plug. You should feel only the end of the plug.

If you feel most of the plug outside the ear canal, remove plug and repeat fitting. Listen to steady, loud noise with plugs in both ears. Cover ears with tightly cupped hands. Noise should sound about the same whether or not ears are covered. If you cannot obtain a good fit, try a different type of hearing protector.
