No, I was thinking of designing and 3D-printing a magnet holder clip -- didn't realize someone else thought of it too. I guess what they say is true, there is no unique new ideas.

Is what you saw just a couple clip on magnets (like what I was thinking), or is it a two-piece cord held together by magnets (like the previous comment mentioned)? That would be cool if someone already makes this as a product.

The product was a full integrated cable. I won't buy it for that reason as I would 1) like to retrofit my existing cables and 2) be able to choose the cable for the spec of the cable itself. If you made a clip and magnet for retrofitting on existing cables I would buy it if it was offered for a reasonable price.
