To activate noise isolation on your Monoprice MPR-8321 Isolating Earbuds, follow these steps using your iOS or iPadOS device: First, make sure the Control Center is visible on your screen. Next, while the earbuds are in your ears, touch and hold the volume slider. Keep holding until extra controls show up. In the bottom-left corner, you'll see the Noise Control icon; tap it. You'll then see a menu with three choices: Off, Transparency, and Noise Cancellation. Choose Noise Cancellation to block out external sounds. 'Off' disables the feature, while 'Transparency' lets some ambient noise through. Enjoy your improved listening experience!
