I noticed the same. I have more bass quantity on the right side and sometimes I think it's missing on the left side completely. Then again, I sometimes have a track where the bass is coming from the left, so I usually put it off as a seal issue.
Before I bought my pair, I auditioned and rented a different W4. It was exactly the same with this one. For now I think that my right ear canal is a wee bit smaller and thus the Complys are pushed together some more, resulting into even better isolation and bass emphasis.
Also, even if this is not the case, I once had an eardrum perforation so I would not let my ears judge about bass quantity. (Everything should be back to normal by now, though.)
 
I was thinking about looking further into this by using tri-flanges or extensively comparing bass tracks with different earphones. However, I might be scared of the result also. Should there really be a difference, I rather not know and not bother about it.
 
All in all, a driver mismatch is posible, but it is by far not as bad as Sylaw's spelling! So I don't really care.

I'm not an audio expert but does this mean anything?

I guess other people had the same problem that's why westone made the 4r?

FWIW, My Westone 4R don't suffer from any channel imbalance..

It took me around three weeks to notice it with my W4. But like I already said, I sometimes still don't notice it.
 
But yeah, good for you.
