- Make sure the headset (and esp. the microphone) are allowed to be used by applications in the privacy settings.
- Set the headset as the default device, for both input and output in the sound/audio settings.

It appears that the headset is not properly paired with the receiver. To pair the receiver:
- Make sure the USB receiver is connected to the PC and the headset is turned off.
- Place the headset very close to the USB-receiver. This step is very important for pairing. Headset and receiver must be almost in direct contact.
- At this point, press the headset's power button until you hear a kind of noise or beep, at that moment DO NOT release the button, wait a couple of seconds more until you see that the light on the USB receiver has stopped flashing.
- The receiver and headset are now re-paired.

It's not possible to provide a replacement receiver for this product.
This is due to the fact that during production the product and receiver receive a unique code, so the product can only communicate with the bundled original receiver.

If the dongle cannot connect to the headphones, the LED on the dongle will flash. Try to unplug the dongle and plug it back in after a few seconds to reconnect the headphones.

Does it only happen when you use it wirelessly, not when you use it wired?

If yes, make sure that other devices close by don't cause wireless interference, e.g. routers, cables, phones.
We would also advise to keep wireless as well as metal objects away from the (USB-adapter of the) headset. And to make sure that the USB-adapter is connected directly to the USB-port without using a hub or extension cable.
