They all die at the very root, and I have the third one dying on me. Unrepairable due to it being cast into some plastic. All "cable-free" converters are passive only, and I have to buy these DACs from an online store, as the local electronics store now only carries super cheap wireless (about as cheap as a proper wired, but godawful of course) ones.
Since building a time machine that would bring me back in time to stop the publication of the art that inspired wireless earbuds (it was some cyborg anime girl listening to music on earbuds without wires, at least the super-thin and transparent smartphone is far away), I thought I'd add some proper cable strain relief to one of these converters.
