Did changing the direction the pair were pointed change this? It's not
at all uncommon when recording in stereo for the sound levels to differ
from the two sides. The mics are recording different soundfields. The
indicated level includes everything going on in each soundfield, not
just the subject you are paying attention to. Often low frequency
background sounds are a major contributor.
You can, in fact zero in on a caller and place him mid center by
watching the metering. Though I consider that a bit dull way to record.
Just like photography you want to place your subject a bit off center
for better composition.
I try to watch for a persistent imbalance between the two channels and
reposition to maintain a better balanced field. Unless I'm deliberately
recording unbalanced for some reason. This is where listening with good
headphones while recording comes in.
As far as if there is something wrong, the difference is minimal, but
you can test with a fixed sound source.
