Jawbone, Verizon VX6800, and listening to MP3's

[Bookman375]

Background noise was killing my communications, so I bought the Jawbone bluetooth unit. It's fantastic, but I was baffled as to how to listen to an MP3 over the Jawbone. After sending an email to Jawbone support, asking if they support A2DP, I received this reply:

Jawbone doesn't support A2DP. However, if your phone trasmits audio through the voice channel (SCO), you should be able to establish a Bluetooth connection between the jawbone and your cell phone and play your music file.

A number of searches on "SCO" and "Audio through voice channel" have yielded nothing fruitful. Can anyone decrypt this cryptic reply for me?
