Decent TRRS cables are hard to find. They are often poorly made, too long, or just not up to spec. Note that you want TRRS, not TRS. They're covered in a nice thick braid and have an anodized metal body. For using the separate keyboard of the QMK firmware they are just perfect. The 1 foot length is just right to give you enough space between the two halves and is strong enough to hold up over a table. I use them with Quefrency and will probably replace most of my detachable keyboard cables with this product. with time.
