"Excellent!"4.5 starson by ryork272
Pros: Sound quality on both ends. Comfort. Volume controls. Instant pairing.
Cons: Voice commands sometimes did not work. Maybe its just me.
Summary: I give this unit 5 stars. Forget aboutt the size. I was a little worried about that when I first saw it on display at Best Buy. Once you put it on its really not that big and its super comfortable. Call quality is exceptional and the noise cancellation is simply the best in the industry. The minor quibble is the voice command feature didn't always recognize my commands. Its either me or the noice cancelling interfered. Regardless, its not a big deal since everything else about this unit is so pleasing.
I tried a Jawbone Icon Hero and returned it. I did not like it at all and call quality faded in and out. It also does not have volume controls. I've owned other Plantronics units and every one of them is better than the Jawbone. Its just better technology and it spoils you.
Not so with this unit. It has a volume rocker right on the unit itself. If you want the best call quality with top notch features, this is the unit to get. I highly recommend it.
