3M™ E-A-R™ Flexible Fit Earplug

A new, one-hand insertion method is offered in addition to the traditional twohand method. Both methods carry their own attenuation rating. 3M is not changing how push-to-fit earplugs have traditionally been inserted. We are only adding a new option.

Flexible Fit is made from a patented TPE foam, which is different than our traditional foam earplugs. This allows Flexible Fit earplugs to be washed with mild detergent and water, and to be reused for up to two weeks after first use (if undamaged, soft and pliable).

Laboratory REAT testing used to derive attenuation ratings requires fitting the earplug according to the written instructions.

Therefore, using a fitting method different than the one specified by the instructions will invalidate the attenuation rating. Always read and follow all Fitting Instructions (PDF 906KB).

Not necessarily. Although the two-hand fitting method carries a higher attenuation rating, neither rating can be relied upon as a precise indicator of the attenuation individuals will achieve. This is due to variation in ear canal size and shape, wearer motivation and fitting skill.

That is why 3M recommends individual fit testing of hearing protectors to validate the level of attenuation individuals can get from a particular hearing protector (Personal Attenuation Rating).

One-hand

• Able to insert when only one hand is available
• Users preference for ease of use and convenience

Two-hand

• When a higher attenuation rating (NRR/SNR) is required or preferred
• When a consistent method is desired for all available hearing protectors across an organization

Users can use whichever hand they prefer. Regardless of which method is used, the same insertion technique should be used when fit testing so that fit test results reflect the fit of the regular hearing protector as it is worn on the job.

Replace earplugs immediately if the foam tip is damaged, detaching from the stem, or is no longer soft and pliable.

Insert until the sides of the cone-shaped tip are inside the ear canal and not visible.

Individuals with larger ear canals may find it necessary to insert even deeper.

Individuals with small or sharply curved ear canals may not be able to achieve this insertion depth. In such cases, an adequate fit may be possible, but should be verified by fit testing. If fit testing is not available, use a different hearing protector.
