Few months ago I purchase Bose QC 35 II but now I’m receiving a hissing sound in my right earphone when the noise cancellation is on both high and low. When noise cancellation is off the hissing stops. I’ve had a look online and seems a reoccurring issue. Does anyone have any experience with this or something similar and what was the outcome?
I knocked the seller he said me this problem did not come with the warranty support.
