Mack's ThermaFit Soft Foam Ear Plugs

Mack's ThermaFit™ Soft Foam Ear Plugs are an excellent all-around hearing protector, ideal for a wide variety of applications. With a good NRR of 29, Mack's ThermaFit™ Ear Plugs are tough enough to block noise from power tools, shooting sports, and stadium events.

What really sets Mack's ThermaFit™ Ear Plugs apart, though, is their heat activated fit. Like any other foam ear plug, Mack's ThermaFit™ plugs must be rolled down prior to insertion. Once the plugs are inserted into the ears, they then expand to fit the inside of the ear canal. ThermaFit™ ear plugs' heat-reactive formulation makes these ear plugs especially good at adjusting to fit the ear canal, as the foam reacts and softens in response to body heat. This enhances fit and greatly improves comfort.

With good NRR 29 protection from noise, and with heat-reactive foam to create an extra comfortable fit, Mack's ThermaFit™ Soft Foam Ear Plugs are ideal for a very broad range of settings and activities:

  • Sleeping
  • Studying
  • Relaxing
  • Working
  • Shooting
  • Travel
  • Using power tools
  • Stadium sports events

Product Reviews for Mack's ThermaFit Soft Foam Ear Plugs (NRR 29) (40 Pair Bottle)

Mack's ThermaFit Soft Foam Ear Plugs (NRR 29) (40 Pair Bottle)5LisaJuly 18, 2019I've used this style for at least two decades. I've tried nearly all the others but went back to these. While I'm falling asleep, it puts any sound in the background. That allows me to fall asleep. Then, once I'm asleep, I can't remember ever hearing anything. One tip I didn't know until I saw a video on this website. Remember to roll them in your finger into a Tootsie Roll shape, as hard as you can, just make sure they're no creases. Then they insert better/further which makes them have a much more snug fit and work better.
Mack's ThermaFit Soft Foam Ear Plugs (NRR 29) (40 Pair Bottle)5Dennis A SmithApril 27, 2019Been using these for years. Wouldn't use anything else. Great great product.

Mack's ThermaFit Soft Foam Ear Plugs (NRR 29) (40 Pair Bottle)5CarolJanuary 17, 2019I have tried many, many ear plugs and the only ones that truly work for me are Mack's ThermaFit Soft Foam Ear Plugs. I can't find them on sale where I used to get them, so I'm thrilled to have found them at the Ear Plug Superstore online! Easy ordering, good pricing, prompt shipping, perfect product--thank you!
Mack's ThermaFit Soft Foam Ear Plugs (NRR 29) (40 Pair Bottle)5Michele CroteauJanuary 9, 2019I have tried soooo many kinds of ear plugs over the years. These are the only ones that work to virtually cancel extraneous noise. I can still hear my alarm, but nothing else wakes me up!
