I have owned a Plantronics 220 bluetooth headset for a couple of years. I have always wondered if I could listen to music off of my smartphone and stream it through my headset. It turns out that, yes, this is possible.
The following are instructions for the HTC HD2 telephone and Plantronics 220.
1. Pair the headset and the phone.
2. Go to START>SETTINGS
3. On the SETTINGS screen, choose MENU from the bottom. On the popup window, choose ALL SETTINGS
4. You will see a screen that has several icons. Choose the BLUETOOTH icon.
5. This is the bluetooth settings screen. If you have paired your device with the Plantronics headset, you will see the headset listed here. Highlight it and then click on the settings icon.
6. Now click on the ADVANCED link. This will expand a menu with several more options. One of the options is AUDIO. Click on the AUDIO link.
7. You should now see a link with a check box that reads PLAY SYSTEM SOUNDS ON REMOTE HANDS-FREE DEVICE. Check that box and click DONE.
If you have followed the above steps, you should now be able to hear music stream through your Plantronics 220 device.
