I picked up a new pair of headphones last night: wireless ones. A previous pair had worn out and I decided to try the freedom of not trailing wires across the desk. I have to say that I am very pleased with the result. Not only do I avoid some of the wires across the desk (well, once I figure out where to put the base unit) but I can wander around the house and out into the garden without loss of signal.
I still need to give them some more testing to find out how well they work with the balance of usage and recharging but so far I am very positive about the upgrade.
