Why is there distortion (static, crackling or hissing sounds) coming from my Harman Kardon ONYX Speakers?

  Brandon LeonJul 26, 2025
  Distortion, such as static, crackling, or hissing sounds, from your Harman Kardon Speakers can stem from a couple of issues. First, the audio source or the source material itself could be the problem; try testing your HK Onyx with an alternative source to see if the issue persists. Secondly, the volume level from your auxiliary device's output might be excessively high. In this case, check the volume of the source and reduce it if necessary.

  If your HK Onyx unit isn't charging, the issue might be related to power supply. First, verify that the wall outlet or power strip you're using has power. Also, make sure that all the relevant switches (for the outlet/power strip and the unit itself) are turned ON.

  If there is no sound coming from your HK Onyx Speakers, it may be due to a lack of power. Ensure that the wall outlet or power strip is receiving power and that all related switches are turned ON, including those for the outlet/power strip and the unit itself. If you're running on battery, ensure that the battery is adequately charged by plugging it into an AC source.

Why does my Harman Kardon Onyx speaker emit a loud hum or buzzing noise?

  Marcus HooverAug 17, 2025
  A loud hum or buzzing noise from your HK Onyx speaker can be caused by several factors. Start by checking the input cable connection to ensure it's properly plugged in. If the cable itself might be faulty, try replacing it. Also, this issue might happen due to ground loop (an unsuitable connection), so try turning the HK Onyx OFF and connecting it to another wall outlet.
