This is then quickly measured by the headphones' internal electronics to produce an opposite sound, which is fed into your ears. Toggle ANC on and tiny microphones on your headphones pick up that irksome engine thrum. When you're using it, you'll soon notice ANC will drain your wireless headphones' battery at a faster rate. Some manufacturers may say their headphones boast a "noise-isolating design" or "natural noise-cancelling abilities", but that doesn't necessarily mean they are 'proper' active noise-cancelling headphones.Īctive noise cancellation is a technology it's an electrical feature that requires power to work.

Noise-cancelling tends to go hand in hand with wireless Bluetooth connectivity, too, also giving you the freedom of no wires, plus a battery life that often pushes north of 24 hours. Most pairs of ANC ('active noise-cancelling') headphones not only include microphones to cancel out external sound but also to allow for chatting to friends and family, or for those video meetings that are all the rage right now. And every model we've recommended below fits that bill. Of course, we're only interested in noise-blocking headphones that also sound great when you do want to listen to some tunes (or watch a film or TV show, for that matter). In fact, many people use them even when they're not listening to music, just as a way to create some silence in which to concentrate – and with those people, we empathise. The best noise-cancelling headphones are great for allowing you to do just that.
