Milwaukee 2191-21 REDLITHIUM™ USB Bluetooth® Jobsite Ear Buds
Premium Balanced Sound. Active Environmental Awareness. Hardcore Jobsite Durability.
The Milwaukee 2191-21 REDLITHIUM™ USB Bluetooth® Jobsite Ear Buds deliver an uncompromised, powerful audio experience engineered exclusively to survive the daily hazards of industrial worksites. Built with water, dust, and impact-resistant electronics, these rugged wireless earbuds allow commercial electricians, carpenters, and facility techs to stream music and take crystal-clear phone calls without worrying about sweat, sawdust, or accidental concrete drops.
Safety and trade focus are seamlessly blended through Milwaukee's proprietary Jobsite Aware Mode. This advanced audio intelligence technology provides active situational awareness by instantly compressing loud external workplace noises—like hammer blows, concrete drills, and engine revs—while keeping human speech clean and clear so you can communicate with your crew without removing your hearing protection. Equipped with specialized passive foam ear tips, the earbuds yield a certified 25 Noise Reduction Rating (NRR) to shield your ears from long-term hearing damage. Powered by a heavy-duty REDLINK™ managed charging case, they deliver 10 hours of standalone battery life and a massive 70 hours of total runtime by cycling through multiple in-case charges.
Why the Milwaukee REDLITHIUM™ Wireless Jobsite Earbuds Are a Trade Essential:
- Jobsite Aware Ambient Pass-Through: Actively minimizes the harsh volume spikes of heavy machinery while sharpening surrounding speech and warning signals.
- Certified Passive Hearing Safety: Includes expandable memory-foam tips yielding a 25 NRR rating and flexible silicone tips providing a 22 NRR rating for workplace compliance.
- Massive 70-Hour Total Power Grid: The included rugged charging case is powered by a removable REDLITHIUM™ USB battery, supplying up to 7 pocket-sized full recharges.
- Bluetooth® 5.1 Long-Range Range: Keeps your audio streaming seamlessly without dropouts or stuttering up to 55 feet away from your phone or tablet.
- Jobsite-Proof Structural Design: Hardened exterior housing is fully sealed against heavy rain, fine metal particles, and accidental tool bag drops.
