Razer Nari Ultimate lost usb receiver

Hi friends, unfortunately I lost the USB receiver for my Razer Nari Ultimate headphones while moving to a new house. I am extremely satisfied with the headphones, but unfortunately they are unusable for me without the USB receiver. It's a shocking fact to me that I can now take and throw away headphones that I bought less than two years ago for $200+ because I can't buy a new USB receiver. Model: GAMING HEADSET Model No.: RC30-026701 WIRELESS USB TRANSCEIVER Model No.: RC30-0267 Could someone advise me how to get out of this unpleasant situation? I like the Razer brand a lot and am very happy with the products, but this is really shocking to me. Mamboh
