Rob,
I have used the Jabra JX 10 and the JawBone with this phone.
I like the Jawbone as it has awesome Noise Cancelling. (You can buy at cingular stores). It's pricey but the people you are talking to will love how good it sounds. (Unfortuneatly the Noise canceling is for outbound, not inbound. go to Introducing the brand new Jawbone Bluetooth headset and see the demos).
any blue tooth headsets to stay away from? the jabra x 10 was panned at retailers ratings, have then impproved it , does the noise cancelling work as well as they say?
When my Dog ate my Jawbone (DOGBONE), I went back to the JX10. I then ordered another JAWBONE ASAP. Not sure if that tells you anything. but i have had 2 JX10's (Dog ate one of them too). they were expensive as i got them when they first came out.
So, between the Jawbone and the Jabra headsets, i have spent over $400. I like the Jawbone so much, when the first one was destroyed, i had to get another and not go back to the Jabra (which is sitting in my drawer).
