Bose’s latest earbuds are designed to help you tune in to the specific sounds you want to hear from the world around you. Hearphones are a sort of blend of noise-cancelling earbuds and hearing aids.
There are several presets in the app, with names like “focused conversation,” “gym,” “airplane” and “television.” You can opt to crank up the volume on all sound or turn it down. You can block out noise or amplify it from certain directions. For instance, you might use it to help you better hear a specific person in a crowded place.
