Should i get the jawbone icon series thinker or the plantronics savor M1100...

[eee]

...Bluetooth headset? Not sure which is better to get or if they stand equal to each other. I need a 2.0 Bluetooth version with a2dp which both have. not sure if all 2.1 Bluetooth are compatible or not. or if i should just stick to plantronics and if so is it 2.0 compatible?

Thanks.
