Which electronic ear muff should you pick, Walker's Razor Slim or Howard Leight Impact Sport?
Choose Howard Leight Impact Sport for directional microphones and its 4-hour automatic shut-off; Honeywell lists both.
Choose Walker's Razor Slim for the maker's slightly higher NRR label and 2 omnidirectional microphones.
For weapons noise, NIOSH recommends earmuffs worn over correctly fitted earplugs; our shooting ear protection guide explains fit and double protection.

Decision table
The table uses each maker's published specifications. NRR is a laboratory label, not the protection every wearer gets after glasses, hair, and a hurried fit enter the picture.
| Attribute | Walker's Razor Slim Electronic Ear Muffs | Howard Leight™ Impact® Sport Electronic Protective Earmuff by Honeywell |
|---|---|---|
Noise Reduction Rating (NRR) | 23 dB | 22 dB passive |
Microphone type | 2 high-gain omnidirectional microphones | Built-in directional microphones |
Audio input | 3.5 mm AUX input jack | 3.5 mm AUX input jack |
Auto shut-off | Not listed by the maker | 4-hour automatic shut-off |
Headband | Comfort headband with metal wire frame | Soft headband |
Who should pick which
Consider Walker's Razor Slim
Walker's lists 2 omnidirectional microphones, NRR 23, a recessed volume control, and 2 AAA batteries. The current maker specifications do not list automatic shut-off.
Consider Howard Leight Impact Sport
Honeywell lists directional microphones, NRR 22, and a 4-hour automatic shut-off. Auto shut-off is not exciting. Dead batteries are worse. Its Air Flow Control name refers to the acoustic cup design intended to reduce bulk, not airflow across your ears.
The honest limit
TactiCool Gear does not test gear in-house. This comparison organizes maker-published specifications. Fit, seal, glasses, and head shape can matter more than a 1 dB difference on the box. OSHA workplace estimates may apply a 50% safety factor to NRR, but that is not a personal impulse-attenuation result. Fit and seal still come first.
