Works flawlessly to adapt my audio interface to my studio monitors, which have a 3.5 mm jack (they also have the possibility to connect through TRS connection, but this adapter saved me some money in cables). The colors make it easy to identify left from right when you plugged them to your 6.35 mm sockets. I use this Y cable with a 6,35 mm to 3,5 mm adapter and they both work very well together, tightening themselves to each other firmly. It even comes with a small Thomann cable tie, but, because of the length of this cable, I don't think I'll be using it. Nonetheless, great to have the tie and not need it than the other way around. Highly recommended product.
