Anything else to try to get Bluetooth properly working on my Treo 700wx?

I currently have the Treo 700wx but am taking a good hard look at the HTC Mogul since it is a smart phone that has Windows on it and does not seem to have any problems with headset randomly disconnecting.

I've tried a few headsets, most recently the Plantronics 655, there are many times it will say my headset is connected, but when the call comes in it wont be. The only way to try to get it back on is to reset the phone and then try to relink it up. I have tried reloading my phone, swapping out my phone, everything that I can think of to no avail. Is there anything else anyone can think of that I can try before I give up on my Treo? Maybe its' just really bad luck, I have no idea.

Also another reason the Mogul intrigues me is thta with it and Microsoft Voice Command 1.6 loaded, I can hold the button on the headset and say the name of the person I want to call and it will call them without any problems. Voice Command through bluetooth headset as far as I knew never worked on the Treo 700wx.

Anyone have any suggestions for me that could help at all?

Thanks,
