I have the Jawbone 2 and the plantronics 925 (I think it is. it's the triangle one mentioned above), and a blueant z9i.

My mini review:

JB2 is nice, but if it doesn't fit your face well, it's going to be the worst you ever had.

Plantronics is nice. Bit flashy, clear incoming and outgoing.

Z9I. You must do the firmware update. If you don't, it'll sound crappy on the TP. Afterwards, clear incoming and outgoing.

For pure noise cancellation, JB2 beats them both, but without a good fit, forget it.

I also have access to a Jabra BT3030 and the Motorola S9.

S9, it's ok. it's both bt headset and bt audio. The ear pieces are awkward and large and can cause your ears to be "sore" after a few hours use.

The Jabra BT3030 is also both a headset and bt audio. You CAN use any preferred earplugs with it as it uses a std 3.5 jack for output. Very clear output, but I've had some complaints of not being loud/scratchy when talking. I use it with some extremely $ headsets and it's surprisingly great for music.
