Bluetooth Video Sync

Delay HTML5 video frames to match Bluetooth headphone latency.

Bluetooth Video Sync helps fix Bluetooth headphone delay on YouTube by delaying the video to match your wireless audio. Bluetooth headphones, earbuds and speakers can sometimes make the audio arrive slightly late, causing lip-sync issues when watching videos. This extension gives you simple manual controls to bring the picture and sound back into sync. Features: • Delay YouTube video by a precise number of milliseconds • Use common Bluetooth sync presets • Fine-tune with small adjustment buttons • Type an exact delay value manually • Save delay settings for each site • Use the built-in calibration tool to find a good starting point • Works locally in your browser • No tracking, analytics or account required Why install it? If voices look slightly ahead of what you hear, this extension lets you compensate quickly without changing your headphones, browser or computer setup. It is especially useful for Bluetooth earbuds, wireless headphones and speakers that introduce noticeable latency. Current beta focus: Bluetooth Video Sync is currently focused on YouTube and standard HTML5 video playback. Known limitations: Protected streaming services such as Netflix, Prime Video and Disney+ are not supported. Very high-resolution or high-frame-rate videos may use more system resources. The calibration tool gives a useful starting point, but some manual fine-tuning may still be needed. Privacy: Bluetooth Video Sync does not collect, track, sell or share any personal data. Delay settings are stored locally in your browser using Chrome storage.
