The Insta-Mold Hearing Protector is a permanent solution & has a *3 to 4 year average lifespan. Compare that to the continuous replacement costs of disposable foam earplugs.
* The actual hearing protector can last up to 10 years but due to constant change in the cartilage of the ear we recommend a new pair of every 3 to 5 years. If there is severe weight gain or weight loss a new fitting will be required as well.
Below is a quick cost comparison chart reflecting the widely used "uncorded" foam disposable earplug ($ 0.15/pair) versus a set of corded Insta-Mold Hearing Protectors. This example makes a conservative assumption that an employee will use the only two pairs of "uncorded" foam earplugs each day for a total year of 250 work days. ("Corded" foam earplugs are generally $0.15 to $0.20 more expensive per pair)
