I've been pulling my hair while trying to transfer phone calls to my HBH-DS970 headset. It neither works when I have an ongoing call and select "Transfer sound", nor when someone is calling and I press the small phone button on the HBH-DS970 (where the mic is). I have no problem listening to music in them though!
When I select "Transfer sound" and select the headset, I get the message "Cannot connect to HBH-DS9701". In the "Call settings" I've selected "Always route answered calls to Bluetooth".
When I try to answer the phone, I get a serie of short "tut-tut"s in the headset, and finally it closes down the connection to the headset.
