cmnybo comments on Fairphone unveils Fairbuds 2 with replaceable battery, Sony LDAC and ANC

I use headphones and a bluetooth transmitter that support aptX LL. The latency is less than 40 milliseconds, which is barely noticeable. With other codecs, the latency is hundreds of milliseconds, so you have to mess with sync settings in the video player.

Most video players or operating systems just handle that for you…

What players and operating systems handle that automatically? I have to adjust it manually in VLC and Kodi. It's usually around 500-600 ms on Android phones and FireTV sticks. Linux isn't as bad, but it's still around 100 ms.

I’ve never had to think about it on iOS, macOS, or Windows. The video just holds for a few frames until the audio buffer catches up to it and then it resumes playing the video frames.

I tried with my TV and at max latency adjustment it's still desynced in Bluetooth. Also other sources of video like from games are not synced, especially like video call delays
