This is from my experience one of the very few 3,5mm plugs suitable for pro stage use. I use it for wired IEM and have a full confidence in it's construction.
The quality of the tip is standard from Neutrik, and it has strain relief that actualy does the job. For me this is really important feature for every pro audio cable.
This plug is really small and can be little tricky for soldering, almost impossible if your cable is over 4mm thick - it won't fit the strain relief. Due to that "only" 4 stars overall. But once completed, I believe it's indestructible
