Active Noise-Canceling (ANC) is a technology used in devices like headphones and earbuds to reduce unwanted background sounds. It works by using built-in microphones to pick up external noises, such as traffic or airplane engines. 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, making it popular among travelers and commuters. With ANC, you can create a peaceful listening experience, helping you focus better or simply relax, even in bustling places like airports or busy streets.
