Good Wireless Headphones

I use wireless headphones because I can’t stand the clutter of cords. But I’m not wild about the ones I’ve got:

[ul][li]a pair of Sony MDR-IF240R headphones. I don’t mind the line-of-sight on the infrared, but they hiss and it drives me nuts.
[/li][li]a pair of Sennheiser HDR 120s. They hiss slightly less, but are still annoying, and they are a pain to seat correctly on the charger.

What reasonably-priced (say, under $150) headphones would be better?

Screw wireless.
