I have made custom earbuds for my Bose Soundsport Free wireless and they do not fit into the charging case.
I want to check if it is possible to remove some material in the for the custom made earbuds without interfering with battery or functions by the case itself.
i do similar things all the time as i work at batteries plus as a tech it looks like the insidw tray for the case should snap out with some gentle prying with a plastic razor blade or something similar. you might have to get it started w an exacto chisel blade and the keep going w plastic blade/guitar pic etc… yes i just tried it with the ones i have and that tray snaps in i would assume youd want to pop up both sides and the edge closest to the hinge and lift that side very sloe to make sir no wires are stressed and that the button up front comes out correct if its attached.
