Hi Scott, My wife bought me the Motorola bluetooth headset and dongle from Radio Shack. The plug on the dongle was the smaller 2.5 mm. variety, designed for a cell phone. Radio Shack does not sell the adapter, and I was unable to track one down, so I returned the headset and dongle to the store.

Someone here recently purchased a bluetooth headphone and dongle from radio shack and is using it with the BN. Do you have the catalog numbers? Does the dongle plug directly fit the 1/8 inch jack on the BN or is an adapter required? Thanks The dongle mentioned on the Sendero cool products page seems to require an adapter. Scott
