Klein Tools AESEM1S Bluetooth Electronic Hearing Protection Earmuff

True jobsite safety isn't just about blocking out noise; it’s about keeping your ears protected without cutting yourself off from your crew or your surroundings. The Klein Tools AESEM1S Bluetooth Electronic Hearing Protection Earmuff completely upgrades your workspace safety by integrating intelligent ambient pass-through technology. Instead of forcing you to pull your muffs off to hear a teammate speak, these electronic earmuffs actively amplify low-level background conversations and warning signals while instantly compressing any dangerous impulse noises above 82 decibels.

Beyond hearing defense, this headset serves as your wireless jobsite command center. Built-in Bluetooth 5.1 links seamlessly to your mobile device up to 32 feet away, allowing you to stream audio or take crystal-clear phone calls via the rugged, noise-isolating boom microphone. Engineered for brutal, full-day shifts, the acoustic housing is fitted with ultra-soft memory foam ear cushions and an adjustable, ventilated headband that eliminates painful pressure points and heat build-up.

• Smart Audio Pass-Through: Amplifies nearby conversations and warning details while instantly compressing dangerous jobsite noises above 82 dB.
