It’s not exactly easy to get a good pair of wireless headphones for cheap. If you do, they’re usually not any good. One option I picked up a few weeks ago for my own use is the Photive BTH3 Bluetooth headphones. So far, they’ve been a great pair of headphones. The sound is good and the battery life is awesome. At retail, these headphones run a over $100, but if you buy now, you can get them on Amazon for under $40.
The Photive BTH3 Bluetooth 4.0 headphones claim up to 12 hours of use on a charge and they generally charge very quickly. The padding around the drivers and on the top of the headphones are very comfortable and you should be able to wear the headphones for hours on end.
