Allen 4154 Ultrax Slim Profile Electronic Hearing Protection 23dB

The Allen 4154 Ultrax Slim Profile electronic hearing protection delivers professional-grade noise reduction in a compact design that fits comfortably under shooting caps and helmets. This 23dB NRR rated ear protection amplifies ambient sounds while instantly blocking harmful noise levels above 82 decibels. The taupe finish provides a low-profile appearance suitable for tactical and hunting applications.

What Makes This Different

Unlike bulky traditional ear muffs, the Ultrax Slim Profile features a streamlined design that reduces interference with cheek welds and weapon stocks. The electronic amplification system uses directional microphones to maintain situational awareness while providing instant sound dampening when gunfire occurs. The compact profile measures just 2.8 inches in height, making it compatible with most shooting positions and headgear.

Key Features

• 23dB Noise Reduction Rating (NRR) for effective hearing protection

• Slim 2.8-inch profile fits under caps and tactical helmets
• Automatic sound compression activates in 0.5 milliseconds
• Adjustable headband with padded comfort zones
• Taupe color scheme blends with tactical and hunting gear

The electronic circuitry processes ambient sounds through independent left and right channels, allowing shooters to maintain directional hearing for range commands and environmental awareness. The system automatically shuts off amplification when sound levels exceed safe thresholds, then resumes normal operation once noise subsides. The cushioned ear cups create a secure seal while remaining comfortable during extended wear sessions.
