Question Bose QC Comfort 35 II hissing noise, What should I do now?

[smrahman.tutul]

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?

Where are they buying from?

I purchase to read the review via Amazon link - https://www.amazon.com/Bose-QuietComfort-Wireless-Headphones-Cancelling/dp/B07G95TJ3P

How long is the purchase?

January 3rd and receive 9th January.
I knocked the seller he said me this problem did not come with the warranty support.

If you got them from or through Amazon and they were sold as new you should be able to get them exchanged for a properly working pair. Contact Amazon if the seller won't cooperate.
The problem would certainly be a warranty issue if it isn't a problem with all samples of the same headphones. I would not consider it to be acceptable if it was so returning them for a refund would be your best bet. Contact Bose service if you can't get them replaced.
If they are new but were not sold through an authorized dealer you may have a problem getting them serviced under warranty by Bose.

I complained Amazon and they said to me today to return them.
