Going on a wireless budget: mouse, keyboard, headphone

Hey guys. I'm looking for some recommendations for wireless mouse, keyboard, and headphones. I've had wireless before, but I'm tired of being bothered with lost batteries, switching them in and out, the battery recharger, etc. Right now I'm using the standard usb ball mouse and a usb keyboard. I'm usually on the move and want to go wireless again.

What I'm looking for is a mouse/keyboard that can be recharged via usb. I can just have it plugged in when I'm on a desk and unplug it whenever I move and still be able to use it. Don't need anything fancy like high DPI, weights, lights, macros, and other stuff. In other words, anything $20-30 would do, definitely nothing over $60.

Currently using Portapros, but wireless headphones would be nice too. I've been looking at the Sony MDR wireless line but reviews are everywhere. However, I probably won't mind the minor drawbacks since one can be had for ~$30 used/refurb on eBay. Any other suggestion for budget wireless headphones?

 

For a mouse, the Logitech M515 I have works pretty well. It still takes 2 AA batteries, but they're advertised to last for 2 years minimum. So far I'm nearing year 1 (received the mouse in late Jan 2012) and still using the OEM batteries.

 

As far as batteries for wireless mice and keyboards, they tend to last a long time nowadays, so recharging is a thing of the past unless you use a wireless gaming mouse.
