Abstract
A wearable audio output device (e.g., headphones) having an open design that allows ambient noise to pass to a listener without physically isolating the listener from a surrounding environment. The device may include an open earcup design that may partially or completely surround the listener's ear, and in some examples a portion of the listener's head may be uncovered by the open earcup. To improve comfort, the device includes a floating audio component configured to generate output audio in a direction of the listener's ear without contacting the listener's ear. To reduce an amount of ambient noise, the device may be configured to perform active noise cancellation (ANC) processing using feedforward and/or feedback microphones. The device may include an acoustic structure configured to direct the output audio in the direction of the listener's ear and/or position the feedback microphone(s) closer to the listener's ear.
