Ok so this might be a silly question..but I've been using a sony ericcson headset with my 8300 and it works grear, but the only issue is that is got a proprietary charged, but I really want on with USB (5 pin) as I'm trying to standardise on having only one charger in the car/home etc..and on long journeys the SE one will crap out..

any thoughts/recommendations

Motorola uses mini USB charging port.
