EP3 Sonic Defender

EP3 Sonic Defender are hearing protection earpieces designed with a double-flange-stem that provides a 24 dB Noise Reduction Rating (NRR). They allow safe ambient sounds to pass through while reducing potentially harmful noises above 85 dB using the Hocks Noise Braker filter. EP3s include attached stopper plugs for extra protection and are right/left color-coded, made from hypoallergenic polymer with an adjustable stem for a secure, all-day comfortable fit. The low-profile design allows wear under a helmet or mask or with a phone or headset. Available in clear, black, or orange. Sold as a single left/right set and includes a carry case and a 26" polymer lanyard. EP3s can also serve as earpieces for radio communication systems by removing the Hocks Noise Braker filter, though removal will negate hearing protection. Available in sizes S, M, and L; size M fits most. NSN: 6515-01-549-6448, 6515-01-549-6453, 6515-01-549-6457.
