Foam Plugs – The plugs are made of a slow recovery foam that expands in the ear canal. Most foam plugs must be properly shaped before inserting into the ear to ensure a good seal.

These plugs may be reused only to the point that the plugs continue to re-expand to their original shape and size.

Pre-Molded Plugs – These plugs are made in several sizes because they do not require shaping prior to insertion. Typically there are three flanges (or rings) of increasing size that seal the ear canal as they are inserted. It is very important to select the proper size to ensure adequate protection.

These plugs may be reused for several months. Replacement is required when they change from their original shape, tear, crack, harden, or soften.

 Earmuffs – Earmuffs are made from protective cups that are secured by a headband. The cups are available in different sizes and the bands are adjustable to provide the best fit. The cushions that surround the cups provide the protective seal around the ear. It is important to watch for cracks or stiffness in the cushion and replace them when this occurs.
musicians plugs Musician’s Plugs – These earplugs are termed musician’s earplugs because they provide a flat reduction of 20 dB in sound to preserve the tonal quality of the signal. This is accomplished by a special filter placed in the plug. Typically there are three flanges (or rings) of increasing size that seal the ear canal as they are inserted. There are 2 sizes available.
