Surefire EarPro Sonic Defender Ear Plugs protect your hearing without interfering with your ability to hear routine sounds or conversations. Their double-flanged-stem design fits most people's ears comfortably. The large Surefire ear plugs provide a Noise Reduction Rating (NRR) of 24 dB. These are made from a medical-grade hypoallergenic polymer. This makes the noise-reducing ear plugs clear, soft, long-lasting and durable. It includes a polymer lanyard so you can take the plugs with you just about anywhere. The Earlock retention rings have seven contact points that help lock the earpieces in place for the same fit every time. Use with your favorite music player or game console, and it also serves as earpieces for compatible radio communication systems. The Surefire EarPro Sonic Defender Ear Plugs allow you to hear safe sound levels with the filter caps out.
The sizes (small, medium, and large) refer only to the outer earpieces that fit in the ear's concha bowl and help hold the EP4 in place. Proper EP4 size is based on the dimensions of your ear's concha bowl. Medium fits most people.
