Hear the hazards, block the blasts!
Stay alert and protected with the Klein Tools AESEM1S situational awareness Bluetooth earmuffs—engineered for professionals who need to maintain situational awareness while working in noisy environments. With SMART SENSE technology, these earmuffs intuitively amplify low-level sounds like speech and nearby tools, ensuring you can communicate clearly with your team while staying aware of your surroundings. Additionally, high-impact or sudden loud noises are compressed to a safe 85dB level, offering essential hearing protection without sacrificing clarity. The Noise Reduction Rating (NRR) of 23, combined with memory-foam ear cushions and a vented headband, ensures comfort and protection throughout long days on the job, even in warm and challenging environments.

The unique dual-knob design lets you independently adjust the SMART SENSE and Bluetooth volumes, giving you ultimate control over your listening experience. With up to 25 hours of runtime on a single charge, powered by a USB-C rechargeable battery, these earmuffs are built to last through extended shifts. Noise-canceling microphones eliminate background noise for crystal-clear calls in busy environments.
