I really liked my BT250 went through the wash so i decided to "upgrade". The BT500 is more comfortable to wear than the BT250 due to its thinner design but does not respond as accurately to voice command (Motorola E815 /Verizon) as did the BT250. I also miss the vibrating feature offered in the BT250, easier to aknoledge a call when listening to music in the car. Otherwise this headset has good range and good sound quality. For road warriors you will LOVE the USB charge cable.
