Soft memory foam helps isolate noise while staying comfortable and in place.
When used on our Custom Molded Earplugs, the foam tips will give you the highest Noise Reduction with an NRR of up to 31.
The MEDIUM foam tips are the standard size included with the Custom Molded Earplugs.
Foam tips will wear out with general use, we recommend replacing foam tips every 4-6 months. Replacements can be found on our website: https://www.decibullz.com/foam-tips/
