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.

Apparently nobody is using high-quality wireless digital links.

If one were of the do-it-yourself persuasion, one might be able to cobble
together a high-quality portable listening device out of SP/DIF running over
existing wireless video technology.

I've used a laptop accessing a music server over WiFi for the general
purpose, but of course this lacked real-time broadcast source support. I
understand that there are wireless phones and PDAs that could do similar
things via a local LAN.
