| Product | Listed NRR |
|---|---|
 Howard Leight Impact Pro R-01902 | 30 dB |
 Howard Leight Impact Sport R-01526 (OD Green) | 22 dB |
1. Howard Leight Impact Pro R-01902
Best for Higher listed NRR
For buyers prioritizing a higher listed passive noise reduction rating, the Impact Pro has an NRR of 30 dB. It is intended for handgun and pistol shooting at indoor or covered ranges, as well as other loud shooting environments. The NRR is not a promise of actual attenuation for every wearer.
Directional microphones amplify low-level ambient sound up to four times; amplification stops at 82 dB.
2. Howard Leight Impact Sport R-01526 (OD Green)
Best for Firearm-stock clearance
If firearm-stock clearance is a priority, the Howard Leight Impact Sport’s slim earcups provide room for a stock. Its NRR is 22 dB; that rating does not promise the same attenuation for every wearer.
Directional microphones amplify ambient sounds, and amplification automatically stops above 82 dB.
Which should you choose?
- Impact Pro: Choose it if you prioritize a higher listed NRR: 30 dB versus Impact Sport’s 22 dB. If stock clearance decides, Impact Sport’s slim earcups provide it.
- Impact Sport: Choose it if firearm-stock clearance is your priority; its slim earcups provide clearance. If higher listed NRR is decisive, Impact Pro is rated 30 dB versus 22 dB for this model.
