Some examples of the disclosure are directed to systems and methods for dynamically updating simulated source locations of audio sources within spatialized audio content based on detection of a change in the location and / or orientation of an audio output device (e.g., earbuds or speakers that are optionally worn by a user and are optionally included in a headset). In some examples, the simulated source locations are updated if the change in the location and / or orientation of the audio output device is greater than a threshold amount of change, and the simulated source locations are not updated if the change in the location and / or orientation of the audio output device is not greater than the threshold amount of change. In some examples, a simulated source location is identified in a three-dimensional environment. In some examples, a mode of outputting audio is changed in response to movement of an electronic device.
