The less we hear about a company's customer service, the better.
Now I know there are companies that are known for their bad customer service but don't you think there's something wrong when you tell someone not to worry about buying a product because it's going to be replaced when it's gonna fail?
But you're completely right, customer service shouldn't be praised just for replacing defective units that should be replaced without question in the first place. In fact, I said almost exactly the same thing about Sleek Audio a year or so ago.
wbrownie assured everyone that replacements would come from current stock, and he also said there had been no returns from that batch - but when I asked him what the batch number was for reference, he didn't respond. So yes, it would help if he posted and tried to clear up some of the issues sooner rather than later. Staying quiet isn't helping!
EDIT: I know wbrownie said the amount of defective pairs was very small, and that the white ones didn't appear to be affected, but the white ones are affected and the list of faulty units is growing every day.
