Best custom ear plugs for long factory shifts (and what to avoid)

Thalia Whitney • September 4, 2025

With thousands of options of hearing protection out there, it’s hard to know where to start when choosing what’s appropriate for your employees. And when the employees are working for extended periods of time, choosing comfortable and effective hearing protection becomes even more complicated.

Choosing ear plugs: what to avoid

If employees are exposed to noise for long periods of time, they should have hearing protection that is comfortable to wear all shift long. Otherwise, they won’t wear them.


Uncomfortable universal fit hearing protection

Universal/standard fit hearing protection is often found to be uncomfortable over time. Every ear is unique, so the same level of protection will not be equally realized by everyone using the same product, just because they have taken it from the package and put it in their ear.


Discomfort is one of the main reasons employees do not wear hearing protection when it’s needed. Some may wear them halfway in, but that won’t provide nearly enough protection.


Silicone custom ear plugs

Not all custom ear plugs were created equal, either. Most custom fit products are made of silicone, a soft material. Contrary to what’s expected, soft material leads to more comfort issues than a hard material. Silicone ear plugs must be made slightly oversize to make up for the material’s compressibility. Over a shift, the pressure from the earplug becomes uncomfortable for some wearers.


Silicone ear plugs also have issues with hygiene and longevity. Because silicone is an absorbent material, wax and other contaminants can work their way into the earplug. Not only does this create a hygiene issue, but it also means silicone doesn’t last very long and often becomes more uncomfortable.


An NRR that’s too high

Another reason employee report not wearing hearing protection consistently is because they feel isolated, can’t communicate with colleagues, and can’t hear important warning signals. This is often due to an NRR (Noise Reduction Rating) that’s too high.


An appropriate NRR should both protect your employees, and allow them to communicate safely.
