Is there any way to "tweak" the sound quality?

I have two of them, both in identical machines but otherwise with all 
associated peripheral equipment unique.  One of them is objectionably 
noisy.  The other in no way would compete with the quality of an ATA186, 
but is usable.  It clips the sound in the earpiece pretty badly though.

Hope there is some way of adjusting these things.  I don't think right 
now I could give either of them to a user who would be considered 
"non-beta."

Thx.
