Sound and Video Out of Sync | Bose QuietComfort® Earbuds (2020)
Please use the most recent software for Bluetooth devices, Bose headphones, and 3rd party mobile apps
Some Bluetooth devices do not fully support Audio Video Distribution Transport Protocol (AVDTP) version 1.3 or later. We have confirmed Apple iPhones, iPads and some Android devices use this protocol and we continue to evaluate other popular Bluetooth devices. However, Audio video synchronization may also vary depending on the mobile app being viewed (e.g. Netflix, YouTube). Additionally, if you continue to have AV Sync issues, try playing the video on the mobile device's local browser, such as Safari or Google Chrome, or a locally stored video on your mobile device (photo library).
Reset your product.
Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more information, see Resetting your product.
Try a different app.
If the issue only occurs with a particular app, it is likely related to the app or app settings.
