Well if I were in your situation I would:
- immediately open a ticket via email explaining the problem and asking for a solution. This immediately gets their attention and may bring forward a solution. This protects you as this is within the “no fault” window and you registered in writing the product is not what you expected.
- determine the “no fault” free return period. It varies by how you bought and country. Effectively legally there is a “not as advertised” free return period which expires after a while because you have implicitly accepting the product works. After the free return period ends, the product is accepted as working and then must fail to work to claim warranty. This protects the seller from someone buying to use for months and then get free refund, while protecting the buyer as you have to show evidence it broke. Typical free no-fault return is 14 days. Check.
- if the email doesn’t give a solution in your free return period you should return, if they promised a fix in your no-fault window and then didn’t give a fix, then you can refer back to the email to get a no-fault return.
- if you return them, if then a fix happens you can always buy them again later when they are discounted.
The above is boilerplate recommendation not specific to any vendor.
Specific to this product, the sound quality issue was discussed in this video. I don’t own this speaker but based on the review I feel it is fixable they need to alter the power given to the tweeters, beyond what the EQ can do.
This shows comparison with the previous product, I think anyone here can spot what is said of a “scratchy” treple?
I’d also add Anker has excellent customer support, so work with them.
I see your other comment
That is for sure the safest thing to do, you can always get it again later, takes typically 2 months for the normal discount to match early-bird discount, but let Soundcore email reply if they say known issue and fix is soon then wait.
The above video has a comment
This video claims a firmware update made it worse
These two reviewers seem to be saying effectively the same thing , but the 2nd review says he thinks its cheap tweeters. He also says the bumps “wavey” cannot be removed via EQ, so he’s recommending two Boom are better than one Boom+
