The HBH-DS980 doesnt connect flawlessly with the Kaiser..some functions just dont work. But if you install the Jetware Bluetooth Handsfree extensions you get more functionality.
You can access the call log.
Time appears on the HBH-DS980.
MS Voice Command works perfectly.
Even though there are a few drawbacks, this is the best stereo headset out there in my opinion. Battery life is incredible and audio levels auto adjust for your headphone and the speaker.
