The MM04i utilizes Bluetooth 2.1 chip technology which enables simultaneous pairing to computers and mobile phones, allowing both VOIP and mobile calls to be conducted through the same handset. Featuring auto pick-up/hang-up and auto connect/disconnect, the handset can be used for private calls or via conference call mode within 30 feet of the MM04i base unit. The syncing cradle charges the iPhone during use, providing uninterrupted calls and desktop music playback. The handset is available in two color combinations that accentuate the luxurious design and sanded aluminium face silver/black and copper/taupe. In addition to providing users with a comfortable, unique, and highly functional way to interact with their iPhone, the MM04i also dramatically reduces exposure to the potentially harmful radiation emitted by mobile devices. Data from TUV, the world s leading certification company, reveal that the MM 04i reduces radiation exposure by 96%, giving users a healthy and productive way to use their iPhone by nearly eliminating mobile radiation emissions, which have been linked by long-term medical studies to a variety of health risks including cancer.
