Reason for high volume in right low in left

Why earphone volume is high at one side low at other side

 

[Lutfij]

If it's an analog headphone, possible that the connection maybe loose. Mind sharing the make and model of your headphone and the source of the headphone's connection to rule out a possible culprit?

Try using the headphones on another source. If the problem persists the headphones are bad. Could be a problem with the plug or with the speakers in the headphones. Unless they are expensive it's cheaper to just replace them unless you want to use them as a learning experience.
If the problem goes away then whatever you are plugging them into is has the left right levels or balance mis-adjusted or is broken.
