Custom Fit Electronic Earplugs Care:
Caring for your New Big Ear’s is easy. Any time you are sweating you should wipe off the outside of your ears to reduce the risk of getting moisture in your electronic Big Ears.
We recommend an anti-bacterial Soap and water, on a damp cloth to wipe them off. Careful not to get it into the sound bore.
You will not need any other chemicals or alcohol.
KEEP THEM OFF THE DASH and out of the direct sunlight. I have seen an issue with the Texas Sun.
Some time’s if you have a dry ear canal, I recommend mineral oil, or Neosporin as light lubrication when you insert them, (a minimal coat and be careful not to get it in the sound bore). I happen to have dry ear canals, and by using this I get a much better seal, as well as my helmet, moves around.
If you want to use your Big Ear’s for sleeping be careful of the wires that they don’t choke you when you roll around.
