which bluetooth headset is best? I want to use one in my car and
connect it to Nokia 8820 phone. I had a jabbra one (early model) and
it fell apart physically. it was good but didn't work well if it was a
little windy.

I use the Nokia HDW3 headset... on the basis that a Nokia headset is
'made for' a Nokia mobile. It works very well indeed, and I cannot
complain about anything at all. I had battery problems with the Nokia
HDW2 (the previous model), but these seem to have been solved with the
latest one. It's also small and compact, and doesn't have a long arm
for the mike like other makes. The price is also very reasonable.

Actually I wanted to post this in the answer sction but couldn't find
it. Anyways, I also, like you, had problems with the Jabra headsets a
lot of times. But then I got the  Plantronics M1000. I feel it's
really really good. It's very comfortable. I''ve had it for a long
time now and I personally feel that its the best of all.

Here's a review from an editor.

 Plantronics M1000

"It's hard to pick a winner from these four products since their
performance, feature sets and prices are all very similar. In the end,
we chose the most comfortable and flexible product.

Wearing an earbud for any length of time becomes uncomfortable and we
didn't feel that Sony Ericsson's HBH-20 two-part, wired solution is
the right one for a Bluetooth product, except for specialist
applications. Although Sony Ericsson's HBH-30 doesn't suffer those
disadvantages, we found that it became uncomfortable because of the
angular speaker housing; the siting of the volume controls is also
awkward.

Of the two finalists, the almost identical Jabra/Motorola products
were comfortable and felt the most secure of all.

However, the Plantronics M1000's flexible ear loop makes for long-term
comfort, fits a wide range of ear sizes and allows you to don the
device quickly and then secure it -- important when the phone's
ringing. This leads us to the conclusion that, on balance, the M1000
is best Bluetooth headset on the market today."
