You can snip the crimp ear, but I prefer a different method using needle nose pliers.
In this picture, you can see that the band is held together in three places.
The top two tabs only hold concentrically. The lower tab is bent (to the right in this picture) when the band is assembled, and that bend keeps it from coming apart.
Use a pair of pliers to bend that tab so it is sticking straight away (with one tip of the pliers on the tab, and the other on the left side of this band, all it takes is a gentle squeeze), and then you can grab the end of the band that the tab passes through and it will pop right off the other two locking tabs. At this point you can pull it off with your fingers.
