Like a recent poster, I bought used headphones from a second-hand market for ~60% of retail price. It was described as "like new" and "used for promo" with "nothing wrong with them." They function correctly except that the battery life when fully charged appears to be about 13 hours instead of ~20.
They have a small screw hole in them that appears to be from a store security device. I didn't realize this when purchasing them.
Does Bose recommend people in this situation to do anything?

They look like a display model - The screw hole is there to keep the power cable plugged in as well as a security measure.
While they function, they may have limited capabilities. It could be they aren't updateable, meaning no bug fixes and no future improvements.
It doesn't necessarily mean they were stolen, and I'll leave it at that.
Thanks for reaching out today.
