Most Bluetooth headsets have a delay in the sound that reaches your ears in relation to what your seeing. It varies in the amount from a few, to a few hundred milliseconds at which point it is normally fairly noticeable. It causes what I believe are called lip-sync issues which are pretty significantly off putting.
I've only come across one pair of headphones (actually earbuds) that don't suffer from this (or with a delay sufficiently small that it isn't detectable). But I had to go through some considerable number before I found them... by accident since I'd long given up the hope of finding any when I came across these by accident.
Generally I'd not recommend it since wired headphones don't suffer from this phenomenon.
