Hyperx cloud 3 wireless headset

The headset is in good condition and was purchased on July 30, but the dongle (USB that powers the headset on the device) broke and no longer works. I wanted to buy a new one, but I don't want to risk losing more money. I bought it for 499 I want 300 for it; if you're not buying at this price, don't bother contacting me. Or if you have a USB you don't want, contact me, I'll buy it from you and we can negotiate the price
