I purchased two of these cables to connect the balanced outputs from my Two Notes Torpedo Studio (as well as speaker simulated speaker outputs from a Rocktron Piranha) to the non-balanced inputs of my audio interface, and they work perfectly! I was pleased Thomann stocked these, as they seem to be a rather niche product, given that connections are normally balanced to balanced TRS or XLR.
They're great quality, with no loose parts or obvious weak points, and appear solid enough to withstand many years of use. In particular the metal latches function smoothly on every unit I've tried, which is more than can be said for some XLR connectors! I've had no issues with sound quality at all, and they quite simply behave just like you would expect a cable to.
The length I purchased works great for connecting my racked Torpedo Studio to my audio interface which sits on top of the rack, no too long, not too short. I really dislike having excessively long cables, especially when I know for sure that I'm not going to exceed a given length, so thumbs up for the shorter than usual length!
A worthwhile buy, and very good value to boot!
