The earpiece is a bit big and does not fit in my ear too well. Could be smaller, pointer, and more snug. I usually use earbuds with replaceable rubber tips in three sizes so I can fit the buds to my ear canal. This is more like the iPod headphones that have large diameter speakers that just fit resting in the ear. Not too tight.

Because of the relatively poor fit, the volume is not that great but can be turned up sufficiently. Also the person being called can’t necessarily hear me that well for some reason unless I speak louder than I want.

The Bluetooth connection worked perfectly and the answer button works well.
