MacBook Bluetooth Stereo Audio Capability

I've a nice Jabra320ST stereo hands free headset that I have successfully paired with my Verizon PDA/cell phone as well as my Windows XP PC, allowing me to listen to stereo music files on either device. I'm using a new MacBook at work, and hoping I can pair my Jabra with it so I can listen to iTune music via Bluetooth. The headphone successfully pairs with the MacBook and is in fact recognized by the MacBook as a Bluetooth headphone device but fails to connect - I am unable to listen to music.

Jabra tells me that the MacBook Bluetooth software does not support Audio Gateway, and thus I am out of luck. Is this the real case, or is Jabra just pointing fingers? I'll be stunned if it turns out that this state-of-the-art Mac is unable to let me listen to its state-of-the-art iTunes files through state-of-the-art Bluetooth headphones. What's so seamless about that?
