When you receive your Isolate® ear protectors, you will find a pair of standard and large tips which fit around the barrel of the product. Start with the smallest and work your way up to the largest. Use the foam that is most comfortable.
It is crucial that the tips are correctly seated on the Isolate® ear protectors and that the Isolate® ear protectors are correctly fitted in your ears, to ensure maximum sound blockage and of course, maximum comfort.
