These Sordin SmartEar Impulse ear plugs are made of TPE and they’re wear resistant and flexible. They have a pointed shape that you can put into your ears securely. Their shape allows your ear canals to remain well-ventilated, so your spatial hearing remains intact. The ear plugs can be used in combination with headphones.
The Sordin SmartEar Impulse ear plugs use impulse filter technology by the Dynamic Ear Company. Because of this, they have a standard noise reduction of 19 dB (SNR) and a maximum noise reduction of 33 dB (SNR) for impulse noise peaks of 166 dB. This technology allows you to stay in contact with your fellow shooters, while protecting your hearing as effectively as you can from loud noises like a gunshot.
