"Wonderfully clear sound, incredibly easy setup."4.0 starson by dan70--2008
Pros: Light weight, good looks, great sound and easy to use.
Cons: No USB cable included, not able to upgrade firmware or stream music etc.
Summary: I bought a Blueant T1 for my iPhone 4 and it simply didn't communicate with the phone well at all (it was no better than my 6 year old Micro). Although the T1 has some great features (if you use an Android phone) the M100 seamlessly interacts with the iPhone including it's battery indicator displayed at the top of the iPhone screen.
