I just bought some (fairly cheap) IR stereo headphones. They work ok, but
with a very audible hiss even at very low volume when there is no sound from
the source (PC). This could quickly get annoying. I wondered if anyone could
tell me, is it that I just have a poor quality product or is this sort of
noise somehow inherent in the technology?

What's the brand/model ?

IR links may well be subject to some background hiss anyway. Think of all the IR
sources in the room.
