I think maybe too obscure, and too many possible meanings at the same time.

Cans means headphones to ham radio operators and audiophiles.

Cans means destroyers to those of us who served in the Tin Can Navy.

Cans means rear ends to a variety of people who call their rear ends cans

And you have to admit that the cans you are referring to don't have much in the way of distinguishing features.
