What crews say
Just do it!
I work around running Turbines most of the year and struggle to hear people speak on the deck. My ears would be ringing after work all the time. I called greg and he hooked me up with exactly what I needed. I was skeptical about doing my own molds but their videos walk you through it, plus they give you enough product for multiple tries. After wearing them for a couple of months now I couldn't be happier. They are comfortable, I don't struggle to hear people talking and they block the harmful decibel levels. Worth every penny.

One pair. Years of wear.
Stop buying earplugs by the box.
Foam earplugs are made to be worn a few times and thrown out. Wear them every day and that adds up to hundreds of pairs a year, and a trash can full of them. A Big Ear set is molded to your ears once and built to last 7 to 10 years. Rinse it, put it in its case, wear it again tomorrow.
01
Fits like nothing off a shelf
Shaped from impressions of your own ears, so it seals without rolling, squeezing or pushing, and stays comfortable for hours.
02
Hundreds of pairs, replaced by one
Wear a fresh foam pair every workday and you go through about 250 pairs a year. One Big Ear set is built to last 7 to 10 years.
03
Less to buy. Less to throw away.
No restocking, no loose pairs in every pocket, and far less going in the trash. The practical choice happens to be the better one.
Hand-built in the USA
Made for your ears alone.
Not assembled overseas, not drop-shipped, not rushed. One pair at a time, for one set of ears at a time. We are proud of that, and we think you can hear the difference.
The detail
The Guardian Transformer custom fit industrial earplugs from Big Ear offers two separate levels of protection and communication in one earplug.
The detachable cord allows for selectable protection between NRR 21 dB and a higher NRR 32 dB.
Great for industrial environments with a wide-ranging amount of noise exposure, or those that need to communicate with peers or supervisory personnel on an intermittent basis.
With the removable pop in lanyard, you can fully plug one or both filters, giving you a solid earplug look and feel.
Move the pop cord to all the vent to be open you have an 18/21dB reduction, and you can hear conservation perfectly now that the filters are open.
We use a non-linear filter, and this means that you hear as if you are not wearing earplugs, and then when a loud sound is created, not more than 85dB can come through the filter.
