Don't waste it on this total piece of crap. I bought the H700 after briefly trying one belonging to a friend. It seemed to work much better than the terrible H500 I got free with my phone. It seemed to be less affected by wind and other background noise. But, within a week of getting it, it began to exhibit the same bad habits as the H500. Unless there was absolute silence, I would have to shout for it to understand commands. When, standing in my totally quiet kitchen, it couldn't understand a voice command to "Call Mom's House" about six times in a row, I took it off, dropped it on the floor, and stomped it into bits. The H700 is an absolute piece of crap not worth a nickel. The only headset I have ever tried that is worse is the H500. Motorola may make great phones, but their Bluetooth headsets are absolute garbage.
