Spracht Konf-X Buds In-Ear Headset - earphones with mic

Noise canceling (ANC) headphones use an external microphone to pick up background noise, and, using sophisticated electronics, cancel it out. A battery powers the electronics. Noise canceling headphones work well, when you're trying to eliminate a repetitive drone, such as on airplanes, or the hum of servers, wind, engines or other machinery.
