I use them with Arduino to play sounds. They work well for this purpose. I use them at 1/4W and they are loud enough for my needs. However, I doubt there is any quality control in their manufacture. One has a few scuffs and marks on the metal case, the other has what appears to be burn marks on one of the ports. See photos, how they looked when I took them out of the box.
