I previously owned the H700 headset and loved it but needed support for 2 phones since I carry my personal cell phone and work phone as well during the day. I was disappointed to find out when I opened this that Motorola changed the more universal mini-USB plug charger with a new connector that is proprietary from what I can tell. This headset looks nearly identical to the H700 and works well in every other way but this new connector looks to me like a money grab to sell accessory chargers. I have no trouble using the headset for a couple days without recharging but if I do buy a car charger I will make every effort to avoid Motorola accessories so as not to reward their bad behavior.
