Both wired and wireless noise-cancelling headphones use a microphone to measure the frequency of ambient sounds in your environment and then generate an inverse sound wave. The inverse wave operates at a frequency that softens or cancels surrounding noise so that you can enjoy music or your favorite podcast or the latest chapter in your audiobook at a comfortable volume.
In fact, the biggest perk of this technology is that it allows you to listen at a lower volume than you would otherwise need. This feature may be especially important when deciding on the best headphones for your child. And, since noise-cancellation works particularly well with consistent and ongoing sounds, like the roar of an airplane, noise-cancelling headphones are among the most useful travel devices.
Noise-cancelling earbuds and headphones set you apart from distracting environments. They can help you focus on studying on your laptop in a café, stream entertainment on your tablet or join a virtual meeting, no matter where you are.
