no lip sync delay

No lip sinking.

Let me say that I was worried about lip-sync delay because Bose does not use a Qualcomm chip that supports aptX low latency codec because I want to use my headphones not just for music but also watching TV, movies, and Netflix

It uses the aptX codec, and claims low latency, though I have noted some lip sync delay

The sound quality is very good and i don't have any lip sync delay

Sony MDR-ZX750BN noise cancelling headset, LG Force, and Plantronics BackBeat GO 3; all of them operated perfectly with the Avantree and synced with the TV video and there is no lip-sync delay when I was viewing programs live and watching Blu Ray and DVD movies

And no lip syncing issues either.

Still a slight lip sync delay with
