SC21 Swatcom Pro Impulse Ear Plugs

SC21 Swatcom Pro Impulse Ear Plugs

The SC21 Swatcom Pro Impulse Ear Plugs are reusable impulse hearing protectors designed to reduce dangerous noise levels while still allowing clear situational awareness and natural communication. Developed originally for military applications, these discreet in-ear filters combine advanced impulse protection with all-day comfort for shooting, hunting, industrial, and tactical environments.

Unlike traditional foam ear plugs that heavily block sound and create muffled hearing, the SC21 Pro Impulse filter system reduces noise to safer levels while maintaining speech clarity and directional awareness.

The filter provides a constant 15dB SNR reduction during normal use but reacts instantly to sudden high-energy sounds such as gunfire, artillery, nail guns, and riveting impacts. This reactive technology briefly increases protection during impulse events before returning to its normal operating state.

The universal fit version uses soft in-ear tips designed for comfortable off-the-shelf use without requiring custom moulds. Their compact size allows the ear plugs to fit comfortably beneath communications headsets, earmuffs, or tactical helmets when double hearing protection is required. The ventilated filter system also allows air movement into the ear canal, helping minimise the occlusion effect that commonly causes irritation and unnatural internal sound amplification with sealed ear plugs.

Swatcom designed the SC21 Pro Impulse Ear Plugs to withstand demanding operational environments. The filters have undergone environmental testing for humidity, hot and cold temperatures, sand storms, and extended 12-hour comfort use. Their fully washable construction supports repeated long-term use indoors and outdoors while maintaining hygiene and reliability.

The SC21 Swatcom Pro Impulse Ear Plugs are ideal for shooters, hunters, military personnel, range staff, industrial users, and professionals regularly exposed to sudden impulse noise. Their low-profile design makes them especially effective for users needing hearing protection that works comfortably alongside helmets, communications systems, or over-ear defenders.

These ear plugs work best for users who require situational awareness and speech clarity while still maintaining reliable impulse protection. Users operating in extremely high-noise environments may benefit from combining the SC21 filters with over-ear hearing protection for additional attenuation.

Designed to be worn on their own, they can also be worn under the Swatcom Active 8 or Active 360 Ear Defenders for ultimate hearing protection.

Whether used on the range, in the field, or around industrial machinery, the SC21 Swatcom Pro Impulse Ear Plugs provide discreet, reusable hearing protection without isolating the wearer from their surroundings. Their military-developed filter technology, washable construction, and comfortable universal fit make them a dependable choice for demanding real-world environments.
