I had a similar experience a while ago, I was using the small tri-flanges and one of them was definitely louder. Switching between eartips made me realize they were ok. I suggest you to do the same first, also try removing the filters after trying the tips. Take your time. If you're using your laptop. some players allow to listen in mono instead of stereo. 

 
The OP figured out the issue...  Software issue, not hardware

Yup, it only changes when you plug something in XD  it is easily overlooked   IDK why it does that randomly though

I just checked the balance again on my Macbook when the earphones are plugged in and the balance was off.  I feel kind of stupid now.  The balance was correct when I initially checked it without the Etys plugged in. 
 
The issue has been resolved.  Thanks again!
