It is a Jabra models 250 and 210 (one is the adapter fitting into the headphone slot on the phone - and the other is the earpiece.)
It does not pair with the car - but the adapter might pair with a car devise - would have to read the directions.
As I recall, the Sprint stores carry the bluetooth adapters for their phones - you can buy one - try to link with your car - and if not, return it. Anyone else try this? My car does not have bluetooth on its system.
