I won't try to top the  Doc. from Washington's review. Same experience here. This is the fifth bluetooth device I've purchased and blows all the others away. My purchase of the H710 was on the strength of a friend's use of an H700. He was the only caller with a bluetooth ear device from whom I could hear every word clearly. This H710 is absolutely the best on everything from utility to comfort. Don't even consider any other. A rare home run from Motorola. Quite a contrast from my wife's crap Motor-oh-no V3m Razr phone. (In comparison to my Samsung U900, another winner)
