Siemens HHB-750 bluetooth dongle probelms

I have a Siemens HHb-750 and a BenQ-Siemens S88.
I get the connection to the phone, but I can´t really use it to anything ( for example if I try to play Mp3s with it, the sound comes from the phone´s speaker.
If someone could send the user manual to me or give a briefi info (or any kind of wild guesses etc.) I would be thankful

Cheers

Me too, exact same problem with CX-75. Need advice and a site to download the seemingly defunct HHB-750 Manual....thanks

And I have an I Tech bluetooth stereo Headphone with the exact same problems, works as phone headset, but doesn't let me hear the music, which plays over the Cell Phone speaker no matter what I do.....Help!

That is because the S88 hasn't got the A2DP protocol wich allowes playing mp3 trough bluetooth.
That also applies for CX75
