I sometimes wear Bluetooth headphones paired to a LG TV for noisy films so as not to annoy SWAMBO watching TV in the other room. What I have noticed is you are more aware of the background noises such as people talking in the background or traffic noise. I do not know if this is a feature of a 5.1 audio system as I have never had or heard one but takes some getting used to not to mention annoying at times.
