The earbuds that come with the t-mobile dash are unuseable. I think I have normal human adult-size ears but these things will not in any way, shape, or form fit inside my ears. The circumference is slightly smaller than a U.S. dime. Because the connector plug is an odd shape that seems unique to the Dash, I guess there is no other way to use earphones because none of my other headsets will plug into the phone. This makes the music function completely useless unless you rewire or use bluetooth.
