"Best Noise cancellation PERIOD!!!!!"5.0 starson by bus3001
Pros: Stealth Mode, fit and incoming volume Battery life( went 4 days B4 I had to charge)
Cons: Crystal talk (who needs that when you have stealth mode)
Summary: I drive for a living I've owned them all you name it Buleant V1 & Q1, Plantronics voyager pro,Jawbone 1,2, prime and now the icon and none can cancel out the background noise like the HX1. I've did all the testing i even had the window down on the freeway in my big rig going 55 MPH and there was no background noise( i called my son's voice mail) Love the fit it stays in my ear without the hook. I found my Last blue tooth headset!!
