Somehow when I connect to listen to my music on the mp3 with my earbuds, when someone calls in, to my surprise, they were able to listen to me like a bluetooth earpiece. they hear me very clear too. Its a standard earbuds 3.5 or 3.2 connector im not sure which, and it does not have a mic for which to talk in. Does the droid have its own built in mic and becomes active when earbuds are connected? If so whats the range, there able to listen to me clearly even when the phone is in my pocket or on the passenger seat. They say they hear no interference whatsoever and its like I am in the other room. Is verizon service that good? Can anyone shed some light into this subject for me as I've never experienced this before. Usually in the past my earbuds have built in mics attached to them. The ones I have now are just standard music listening. thanks.
