I've never been a fan of handsfree devices but I really like the quality of this Bose version I have. Better than using my phone, actually.
My iphone is across the room, plugged in... I pick this thing up, click a button, say 'call John'... it uses iphone voice recognition and comes back and says 'John has two numbers', I pick one, it dials, and I'm talking. Same with answering the phone.... Click, 'hello?'
Very cool. Very little. Great sound and mic. No canceling the trial period for me:)
