so I just broke my bluetooth and now I need a new one...I was looking at a Jabra BT530 but I'm not sure which ones are completely compatible with my curve 8320. My last bluetooth wouldn't play my music thru the headset when I had it connected and wouldn't do the ringtones and such either. Any suggestions on good BT headsets? Also, if anyone has the BT530 do you like it?

My husband had the Jawbone and it kept falling out of his ear. Well, when we went to BestBuy to look at BTs, we were told that the ones that were actually Headphones (ear cup type) were for listening to music etc. In other words, the Stereo type. The monos were for mostly phone calls. So I have a little cheapie called BlackBerry HS655+. It's not fancy but it's solid and works for phone calls but not for music. Try any and if it's not to your liking, take it back for a refund and try another. Hope that helps.
And to answer your question of compatibility, any of them should work with your handset.

Most Bluetooth headsets are compatible with BlackBerrys. Personally, I've used Motorola headsets for years, as I have found them to be very reliable. Other brands have also gotten favorable feedback here.

It comes down to personal preference. Never hurts to solicit feedback from the people you know, or visit a retail store and ask questions.
