I'm using wireless headphones right now. Of all the many electronic gizmos I've bought over the years, they're possibly the most useful (and most loved). I wear them for hours every day, listening to internet radio stations from my computer or 'normal' radio stations from a traditional radio. The sound quality is fantastic.
The ones I use currently cost £69.99 in Argos but Curry's/PC World have them on offer for just £46.99:

They're really easy to use. You simply plug the lead from the transmitter part into the headphone socket of a radio, computer or whatever. Then you switch on the headphones and wear them. It couldn't be simpler! (There's a volume control on the headphones, so you can adjust the sound level). When you've finished using them you simply turn them off and plug in the charging lead (which is attached to the transmitter part). A full charge lasts about 14 hours, so there's not much chance of the battery going flat while you're listening to something. The transmitter range is good; I can use them all arond the house and even when I putting the bins out at the end of the street. They're also amazingly comfy too; it's easy to forget that you're wearing them.
