Active noise-canceling is a technology used in devices like headphones and earbuds to reduce unwanted background sounds. It works by using tiny microphones to pick up external noises, such as chatter or traffic. The device then generates sound waves that are the exact opposite, or "anti-noise," which cancels out the unwanted sounds, allowing you to enjoy your music or podcasts without distractions. This technology is especially useful in noisy environments, like airplanes or busy offices. By creating a quieter space, active noise-canceling helps improve focus and relaxation, making it easier to concentrate on tasks or simply unwind.
