OSHA-Compliant Hearing Protection

These in-ear headphones carry a certified 25 dB Noise Reduction Rating for use in construction, manufacturing and airport environments. Medical-grade silicone tips provide a secure seal that blocks harmful sound while staying comfortable during long shifts. The single-ear coupling lets workers maintain situational awareness on active job sites.

Bluetooth 5.3 Connectivity

The headphones use Bluetooth 5.3 to maintain a stable link up to 50 feet from the paired device. A built-in noise-cancelling microphone keeps voice calls clear even when background noise is high. This wireless standard is the single specification that determines whether the earbuds will work reliably with a given phone, tablet or two-way radio.

All-Day Battery and Rugged Build

A single charge delivers 12 hours of continuous playback to cover a full workday or extended travel. The IP65-rated enclosure resists dust, sweat and water jets, while Kevlar-reinforced cabling withstands heavy daily handling. At one ounce the earpiece stays light enough for all-day wear without fatigue.

Questions about this item

What does the 25 dB NRR mean when I am wearing these on a job site?

The 25 dB Noise Reduction Rating indicates the ear tips can lower incoming sound by up to 25 decibels when fitted correctly, helping protect hearing around loud equipment.

What does Bluetooth 5.3 actually limit in daily use?

Bluetooth 5.3 keeps a stable link up to 50 feet from your phone or radio, so you can move around a worksite without dropouts.

What do I need to check so the earbuds stay in place all shift?

The USP Class V silicone tips come in multiple sizes; choose the one that seals your ear canal fully and the Kevlar-reinforced neckband will hold the buds securely.
