JVC Marshmallow ear buds doin't work

Anyone using JVC ear buds? I use the marshmallows b/c of the memory foam bud which stays in your easr while running and also does an excellent job of sound isolation. These worked great on my Galaxy Nexus but they don't seem to work at all in the phone function on the Siii. I can play and pause music with them but the phone does not respond. I have checked with the Samsung set and they work fine with the phone.

Is this a phone issue or know compatibility issue? The exterior of the jack appears identical.
