Firmware Update for Ultra Earbuds?

Forgive me, but I have been out of the loop on Bose for a bit. Did they ever come out with a firmware update for the Ultra Earbuds to eliminate the whining noise in the left earbud? I really liked the sounds of these but couldn't get past that noise.

After 3 different pairs all having the same issue, I finally returned them. Would live to pick them up again if this issue is resolved.
