All earbuds and headphones have some degree of passive noise isolation, but custom-fitted earphones, in-ear monitors and earbuds are by far the best in this regard, as they create a comfortable and secure seal.Īctive noise cancellation is when your headphones or earbuds neutralize the ambient noise around you via noise-cancelling technology. You don’t need additional battery power to take advantage of passive noise isolation. That means you can listen to music at lower volume levels because you don’t have to counteract the sounds of your environment-whether that’s a noisy coffee shop or the loud rumble of a plane engine. When your earbuds are molded to the exact shape of your ears, it prevents outside ambient noise from entering your ear canal. That’s why you’ll hear this technique called both passive noise isolation and passive noise cancellation. In other words, your earbuds are isolating you from ambient noise instead of actively using technology to cancel it out. Passive noise isolation (PNI) or cancellation is when your headphones, earbuds, earphones, or in-ear monitors naturally block outside noise. In this article, we’ll explain the differences between passive noise isolation and ANC in terms of comfort, sound quality, ambient noise reduction and more. Though the goal of both is to block outside noise so that you can enjoy your music with fewer distractions, passive noise isolation-also called passive noise cancellation (PNC)- and active noise cancellation (ANC) couldn't be more different. If you're not sure what the difference is between the two, you're not alone. Two of those terms are passive noise isolation and active noise cancellation. When you're shopping for earbuds, there are a lot of terms you see over and over. What’s the difference between passive noise isolation and active noise cancellation?
