The Peltor H7A earmuff is claimed to be the #1 Selling ear muff in the world. The smooth feel of the spring steel headband is the first thing you notice that sets this hearing protector apart from the rest. The cushions are a three layer affair, with an inner fluid filled cushion that is covered with foam and encased in high quality vinyl. This combination of features makes just about the most comfortable pair of muffs we have ever offered. Peltor refers to the H7A as the 'Optime 101' model. Their point here is that with an NRR 27 rating, you should be able to work in an environment not exceeding 101 decibels and be within safety guidelines. The H7A is manufactured in Sweden, and assembled in the U.S. Weight is 8 oz.
