So I have owned Bose’s truly wireless earbuds, the sound sport frees, for almost 3 years and the batteries inside are on their last legs. My warranty is up, and i don't mind taking them apart, so I would like to try and replace the batteries myself. I have found videos for the regular sound sports that are Bluetooth but wired together, but I would assume that it would be different, due to having just one battery in one of the buds, rather than separate batteries in each of the buds. Overall I would just like to know if anyone has an experience with this, or knows a procedure or parts I would need. Any information is appreciated.
