The time it takes for delivery, I'm guessing some poor Chinese bloke has to swim the whole way from China to the UK with one of those Deliveroo boxes full of OEM/generic/unbranded/fake gear on his back. How is that adding to pollution?
Because if they are rubbish then you have wasted 65p and added to the pollution by having it delivered from China and you will probably throw them in the bin for landfill.
If you have an S9 or S8, just go to live chat and say your headphones are faulty. They send a new pair out.
