Noise-canceling headsets are designed to reduce unwanted ambient sounds, allowing users to enjoy music or focus on tasks without distractions. They use microphones to pick up external noise and generate sound waves that counteract these sounds, effectively "canceling" them out. This technology is particularly useful in noisy environments, such as airplanes or busy offices. These headsets come in two main types: active and passive. Active noise-canceling headsets use electronic components to block noise, while passive noise-canceling relies on physical design to create a seal around the ears. Both types enhance the listening experience and improve concentration.
