No sound in Speakers

No sound coming through speakers / Left & Right speakers have different sound volume / Sound only comes through one speaker. Also happens in-game

In most cases this is due to the cable not fully plugged into the left ear-cup.

Otherwise, please check these steps:

  1. Please make sure that you downloaded the Surround Dongle Software and thoroughly follow the user guide, which you can also download online: https://en-us.sennheiser.com/gaming-downloads
  2. Have you tried the GSP 350 on USB 2.0 Ports? Please do so, as USB 3.0 seems to cause issues.
  3. We don't support the use of third-party devices with our gaming headsets. They can interfere with communication between gaming headsets and computer.
  • Unsupported third-party devices include:
  • KVM switch boxes
  • Port replicators
  • Docking stations
  • USB hubs

NOTE: The manufacturers of these third-party devices implement headset support in different ways. There is currently no industry standard.

  1. Do you have any other audio software installed? If so, please uninstall as it might interfere with sound.
  2. If the issues still persist, you could also try to completely remove the Surround Dongle from your device manager and re-install it, therefore:
  1. The unit is defective.
