E30 Tactical Earphone Earplugs NRR31dB -Tactical Bluetooth Earbuds with Active Noise Cancelling for Shooting Hearing Protection

1. Core Hearing Safety: NRR 31dB Professional-Grade Noise Reduction

Physical sound insulation + intelligent compression: Effectively attenuates sudden high-decibel noises such as gunshots, explosions, and mechanical roars (peaking at 31dB), while preserving essential voice prompts and environmental warning sounds to prevent missing critical information due to complete sound isolation.

 

Hearing Health Protection: Prolonged exposure to environments exceeding 85 dB can cause irreversible damage. This product reduces hazardous sound pressure levels to a safe range (approximately 75–80 dB or lower), making it suitable for workers exposed to high noise levels on a daily basis.

 

2. Wireless Connectivity: Flagship-Grade Bluetooth 5.4 Chip

Faster, more stable, and more energy-efficient transmission: Compared to Bluetooth 5.2/5.3, it offers enhanced interference resistance, an effective connection range of ≥10 meters (line of sight), and audio synchronization latency as low as milliseconds, making it ideal for seamless pairing with devices such as smartphones, walkie-talkies, and tablets.

 

Simultaneous Connection to Two Devices (Device Support Required): Supports multipoint connectivity, allowing for smart switching between calls and media audio so you can balance work and entertainment.
