I just bought some (fairly cheap) IR stereo headphones. They work ok, but

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.

Hi,

These are Pro-Luxe IR-650ST.

They were pretty cheap, and they make me look a bit like a cyberman

I tried shutting the curtains, turning the lights out and switching my
monitor off in case any of that was an IR source, none of it seemed to make
any difference.

One thing is, these phones make an awful racket - about 10x louder - when
the transmitter is off or I cover the receptors. If I had been wearing them
at full volume when I popped the batteries in and switched on, I might have
suffered damage!
