There's not much that can go wrong with something as simple as this right? or so you would think.
This item works perfectly and does exactly what you would expect, until you try to unplug your headphones again. The sockets are so tight that the rubber covering on my headphones pulled away from the plug when I tried to remove them and the only way I could get the headphones unplugged was very carefully with some thing nosed pliers.
I now need to replace an expensive set of headphones as well as buying a new splitter, I guess you get what you pay for. There are plenty of these items on amazon my advice, buy one of those.
