I'm looking for external speakers to stream music from iheartradio, Pandora and Slacker. I went to Radio Shack and the sales rep said the headphone jack on the 8830 is smaller than the standard size, but recommended an adapter to connect to speakers. I connected the phone to the adapter and the adapter to the speakers, but it continued to stream music from the phone and not the external speakers. Any recommendations for this problem? Thanks!:)
