The XLR-jack is of a good quality, doesn't easily come apart. The wire is made with a good thick insulation, which prevents signal loss when bend. The 3.5 mm jack could be build better. The material (metal) is very sturdy, but the adapter came apart easily, because it wasn't enough tighten up.
It does what is should, no audible loss of sound quality, no noise on the cable and no loss of sound.
