I have the Sony wh-xm4 and wf-xm4 buds, when I've watched video on my MacBook with them they will connect with AAC, I don't notice any latency on YouTube or with streamed movies. With my phone I use LDAC at highest quality and don't notice latency with YouTube or streamed movies. I mostly use wireless DAC/amps with LDAC and don't get latency with those either. I don't play any games, I imagine that if there was going to be latency it would be with games.
