Defect in the Soundcore 3 speakers, where can I find replacement parts?

Hello friends, I need help, as I need to purchase parts to repair the Soundcore 3, as the two I have had the same defect: the speakers started to hiss, there was a defect in the cord that connects to the coil. However, I’m not finding the parts. Could you recommend me?

I must have been unlucky enough to get a really bad batch, there were two separate purchases a month apart, from the official Anker store on Ali Express, both products were used very little.

You could ask the support.
But I dont think they can help you a lot.
