How's this for customer support.

I ordered the new upgrade for the Series X headset (better battery life)
back in October (about $125). It was delayed until after January 04
because of a supplier problem.

Mysteriously around Christmas I got a box from Bose, but it was a new
QC-1 non-aviation NR headset. I called about why I got it, and (after
most everyone at Bose had no idea why it was sent) I just got word that
they were being shipped as "atonement" (their word) for the delayed X
upgrade.

No charge, yet it's got to be worth more than the original order.
