I have a new 650 and Treo Wireless Headset. Overall I am satisfied with both products. The wireless headset seems to work fine for me and I did not need to use the jabra earpieces to increase volume or to make it comfortable to wear.

The only problems I have noticed is that there is a delay between the time I dial a call and the time I hear it on the headset. The headset usually picks up when the other party says "hello". I never hear it ring.

Then, when hanging up a call, I have noticed that using the button on the headset immediately hangs up the call. Or, actually touching the 650's screen will immediately hang up the call. But if you use the center button like I am accustomed to doing there is a tremendous delay.

Any fixes for these problems?
