Preferably a dongle, but Bluetooth is ok as well. what wireless headphones do you use? thanks for all suggestions!!!

edit: because i wasn't very descriptive, i will append this: i don't really care about the quality too much, i want to spend ~80 usd or so, but that's flexible within 10 dollars or so. i would prefer a headset that has a USB dongle, like a wireless mouse. i don't really need a microphone in it, but i wouldn't really conplain if there was one.
