Audio problem with headphones

[soniccaner1]

So i have had this audio problem with my headphones where sound would only come out of 1 ear. I have been experiencing and putting up with it for some time but i just finally had enough. I use a 1 to 2 splitter and whenever sound would come through 1 ear i would have to move the wire around till i get sound through 2 ears but sometimes it would go back and i would just get furious as i am doing this whilst gaming. Now my issue is, what is the problem : The headphone, the splitter, the pc.
I have used the case and motherboards sound ports.
Even when i put it in without the splitter i have problems.
And i have actually noticed problems when i use it on my phone too again without the splitter. (starting to answer my own question i think)

yes probably a qed.

most likely culprit is the plug, not sitting correctly in the socket results in mono 1 ear sound.
