I agree, of all the BT headsets I have tried, the 510 is by far the clearest.
Now, as for the 510 working with the 700p, so far nobody in this thread has one that works (even the ones who say it works). If your 510 is dropping its connection regularly then your 510 is NOT working with your 700p. Mine constantly drops the connection. Whenever the phone rings I have to press the Talk button on my 510 ASAP! If I wait more than two rings I'm SOL. If I hit the button in time it takes another 2-3 rings for the 510 to reconnect with the phone. Then when I hear a confirmation I have to hit the button a second time for the headset to pick up the call. If I don't do these things in rapid succession I will lose the caller to voicemail. This is absolute crap.
A BT headset should not drop its connection with the phone at any time. With my 650 I could turn the phone off, turn the headset off, leave for hours at a time and leave the headset at home, I could do whatever I wanted to do and it was no problem. As soon as the 650 and headset were back in range they would seamlessly work, no manual reconnecting and no repairing needed.
Palm desperately needs to issue a BT fix. It's unbelievable to me that Palm actually posted a list of compatible/incompatible headsets which is rediculous. Does such a list of incompatible BT headsets exist for ANY other cellphone? Any BT phone should work, as designed, with any BT headset. Period.
The flaky BT implementation of this phone negates any advantage (and right now there are very few to speak of) of the 700p over the 650.
