I wonder if getting a quote from someone like Gakables for a length that makes more sense for stealthing would be worth the savings after international shipping (or if Ted even ships to the EU, I'm not speaking on his behalf). A cable using chopped shorty connectors and Belden 1804 would be very similar to that and likely half the cost.
Those DPA cables are nice with the tiny little female connector that almost disappears into the mic but the other end is a typical long Neutrik XLR, it's made out of regular small profile Mogami cable (which is great, I use it all the time, but it's not worth 3 dollars a foot at 10m long) and they are really expensive. If it was me I'd call a couple of guitar/pro audio shops and ask if someone could build me something similar for less money.
If the cost is not a hurdle I'd reach out to DPA and get the cost of a short custom made cable. If it is, consider getting a soldering iron or find a friendly tech at a local shop. Before I learned how to make my own cables (and got a side hustle going building them for others) I found a guy at a pro audio shop who would build stuff for me if I brought the parts and gave him some cash.
