Razer Nari Dongle

Could someone help please, I bought a Razer Nari headset a while back and for some time i have been using the aux cable now. The headset worked great in the beginning but after a while it had trouble connecting to the dongle. For a while i stopped gaming for personal matters so i didnt mind having to use the cable instead. But right now im starting to play a lot of games again, and without the dongle my microphone doesnt work. Is there any way to get a new dongle? Ive tried looking for one but cant find it. If someone could help it would really be appreciated
