Exactly. I bought Bluetooth headphones to listen to music at work & home, and it was all fine... until I decided to watch some TV shows in my free time. It was then that I realized I have 0.5 - 1.5s lag in audio (growing with time), which made movies unwatchable. Very quickly I bought two pairs of wired headphones instead.
Something very wrong in the stack there. There should be a delay in the video in order to compensate for the latency sending the audio to your ears (Bluetooth does not add much here but it all adds up) and you should experience no latency.
