This particular type of noise cancellation is typically advised for users at home (or those who aren't mobile), so they can focus on the sounds they want to hear without distractions or outside noise. However, for those that are commuting or need to be aware of their surroundings, using audio devices with passive noise cancellation is generally not recommended. Active noise cancellation (or ANC) is the second kind of noise-canceling technology and is a lot more complicated than the first kind. Active noise cancellation requires mics and an ANC controller as well, to record the ambient sound frequencies and reverse for the audio device to play back. The science behind active noise cancellation has a few inherent limitations, such as: The sound being canceled out must be continuous, such as the sound from an engine. If you're looking to go wireless, there are some choices with Active Noise Cancellation, like the Apple Airpods Pro, Sony WF-1000XM3, Xiaomi Mi Airpods Pro, and Huawei Freebuds 3. Different Types of Noise Cancellation When purchasing headphones or earphones that have noise cancellation, you generally will encounter three types.
