Peltor Tactical 6S electronic ear muffs are lightweight, slim, and affordable electronic ear muffs with high quality audio reproduction and protection.  These muffs use AA batteries, and provide users with a noise reduction rating (NRR) of 20, and have a response time of only 5 milliseconds.

These were my first electronic ear muffs, and they are an excellent value for sound quality, protection, and durability!  These ear muffs are now manufactured by 3M, and carry an excellent warranty, so buy with confidence!
