I previously owned an H300 and was impressed with the quality for the price. When I lost the H300 I decided to try the H700. I was most interested in the improved sound quality and the fit around the ear. In those two areas the H700 is definitely an improvement over the H300. I did not use the voice activated commands, so I cannot speak to that, but I do see where that could be useful.Overall I do see the H700 as an improvement over the H300. My only problem with it, which is why I did not give it 5 stars, was the Bluetooth drop out. It seems that the Bluetooth on the H700 drops out more often than the H300. I would say that it drops out on 1 in every 20 calls.
