The model 330 is part of Plantronics's Explorer series of headsets, comfortable, wearable on either ear, and with all the controls located in a single button. And "all the controls" doesn't mean just volume and start/end, either. It includes last number redial and voice dial commands as well.
With up to eight hours of talk time, this unobtrusive but attractive bit of tech can keep up with your busy day. If you live in a state where you can't drive and use your phone if you have to use your hands, this is for you!
