Actually, we all knonw the transferring latency of WF-1000x and SP700N is nearly 500ms.

However, On Xperia XZ / Xperia XZP, there is no audio latency feeling while watching videos - Suppose the two models integrates Auto-sync Video and Audio delay feature.

But with Xperia 1, the audio is slower than the video - How terrible the experience si!!!

Please add the audio sync feature back! Or provide manual video delay settings for trure wireless BT earphones！

This isn't anything really to do with the Xperia 1, more the earphones themselves.

The support site for the 700 earphones actually says there may be a delay in audio/video:

You could try to update the firmware of the earphones, but best bet is try the Headphones app/Headphone Connect and try changing to AAC from SBS

and failing that, try the developers settings for different bluetooth settings.

AptX or Aptx HD would be the preferred feature of an earphone for audio/video.

These are mostly for music and calls earphones, not really for video playback though.

I used to use the WF-1000x with my Xperia XZ3 and although they were good earphones for music (except the connection dropping out too often), the latency made them a bit unusable for watching video.

Xperia 1 together with my Sennheiser Momentum True Wireless buds works absolutely fine both in terms of connection stability and latency for video. I think the key is having earphones that support aptX Low Latency audio.
