Oh for god's sake. Things like this are ewaste only because people toss them vs recycling them. And if you think most people would DIY battery repair on these, you're naive.

Last time this came up someone linked to their article on 'less evil' BT buds but obviously didnt read it. Even the bud that you could theoretically repair are fiddly as hell and several use special batteries. THey're theoretically repairable but not by 99% of DIYers.
