Mack's Putty 7T Silicone Earplugs 16 Pair 22 dB

Original moldable silicone putty earplugs

Mack's Putty 7T earplugs are the original moldable silicone putty design, first introduced in 1962. They conform to the unique contours of virtually any ear to create a custom airtight and watertight seal. The pack contains 16 pairs and carries a US Noise Reduction Rating of 22 decibels and an EU Single Number Rating of 30 decibels. They are made in the USA from non-toxic, non-allergenic silicone.

Fits any ear without hardware or power

Because the putty molds directly to the ear canal, no headband, cord, battery or electronic device is required. The soft silicone adapts to changes in ear shape over time, removing the need for custom-moulded alternatives. They stay in place during extended wear for sleeping, swimming, concerts, flying or studying, and the waterproof seal helps prevent swimmer's ear and surfer's ear by keeping cold water and moisture out of the canal.

Reusable silicone putty in a 16-pair pack

Each pair can be reshaped and reused multiple times, so the 16-pair supply covers many nights, swims or events without replacement cost. There is no software, app or firmware involved; the only accessory is the carrying case that holds the putty. The material remains pliable across temperature changes, so the same pair works for a cold pool, a warm bed or a noisy flight.
