Hi all,
I use the Jabra 3030 with my Q9 also and I must say that the sound quality is very good.

No complaints there.
I do have troubles with the media player picking up the playback after a phonecall. Most of the time there will be no resuming of the playback (using Windows Media player and after receiving a call) or it will resume after a couple of minutes (so the media player is playing but no sound comes through the headset). This is a bummer!
I have yet to find to a way to fix this.
How are your experiences?
Wouter
