Hi, I have had a set of QC20s for nearly three years. I've recently noticed they have developed a 50hz buzzing noise. at first I thought this was the PC they were connected to, but it also happens when plugged into my iphone. If I ground myself on any electrical item on my desk it goes away. Is there anyhting that can be done to aleviate this?
Hi there @hot_fiat and welcome to the Bose Community!
I'm sorry to hear of the Buzzing audio you've been experiencing here and would be happy to look into this for you.
It's interesting that you note when you ground the device the buzzing stops. When connected to or charging from an un-grounded device, such as a computer, TV or USB wall charger, it is possible for the headset to produce a humming sound.
As such, can I ask if you only hear this when this is connected to power and the device you're using?
If so, is there any difference if you use a power supply with a surge protector (if this is possible to check)?
