View Full Version : Beyerdynamic HS 400 buzzing noise

24th Dec 2016, 13:54
Hi everyone,

I'm using my personal Beyerdynamic HS400 as headset in the A320, on some aircraft I have a really loud annoying buzzing noise. I get this noise when talking, or just when the interphone is active. It's a lot louder when I come closer to the windshield so I think the problem is with the 400Hz static noise coming from the window heating...?
In the pictures below you can see that I have a converter from 2 pins to the airbus XLR 5pin, however, when i opened op the converter I see that 1 pin is not connected?

Do you have any solution how to fix this?
