The Bose B40 builds on the strength of their SoundComm B30. The B40 boasts the same noise reduction technology as its predecessor, along with an updated noise-canceling microphone. Active equalization shapes incoming signals for clear, intelligible intercom audio. A high-performance earcup cushion creates a super-strong acoustic seal without sacrificing comfort, while lightweight materials, intelligent weight distribution, and minimal clamping force enable you to wear your B40s all day long. What’s more, durable, weather-resistant construction withstands everyday wear and tear, along with unpredictable extremes of outdoor use. If you need top-level communication in a noisy environment, you can’t go wrong with the Bose SoundComm B40 Headset.
