A $2,000 earplug business
In 1962 Raymond Benner, a symphony musician, bought a small earplug business from an elderly pharmacist for $2,000. The company was McKeon Products, and its one product was a moldable clay earplug named after the previous owner. Benner, a swimmer, wanted a plug that sealed out water better. After a lot of trial and error he arrived at a moldable silicone earplug, which he renamed Pillow Soft because the plugs looked like small white pillows.
Benner later spent more than 30 years playing with the Cleveland and Detroit symphony orchestras. His wife Cecilia went on the TV show "What's My Line?" twice in the 1960s with "making earplugs" as her line of work. Their sons Devin, now CEO, and Pete still run the company.
One plant in Michigan
McKeon says it "operates solely out of its state-of-the-art facility in Michigan," and its address is on Guenther in Warren. The business moved through eight facilities on the way there, starting in the Benners' basement.
The Pillow Soft silicone earplugs and the Ultra Soft and Slim Fit foam earplugs each say "Made in the USA" on their product pages. Mack's also sells earmuffs, electronic shooting earmuffs, sleep masks and an ear dryer. Those pages give no origin, so we could not confirm where they are made.
