Thanks for the clarification about the audio dongles, Scott. So then I guess my next question is for anybody who may have used one of these with a small speaker and their braile or voice note or PK. Is there a recommended small speaker that would fit on a shoulder strap, like the much discussed wired radio shack one? Or do people prefer an ear piece? I'd be a little concerned about an ear piece because of shutting out environmental sounds whhile walking in town. Mary
