The MINIKIT Neo 2 HD is able to connect to 2 phones simultaneously. You don't have to worry about receiving calls on your personal or professional mobile phone, the MINIKIT will manage both seamlessly. Thanks to the Switch function, you can use both phonebooks to make calls: just push the jog-wheel for 2 seconds to reverse your phones order. And you can stream music from both phones! HD Voice shows a higher definition voice quality and a more accurate reproduction of human voice, resulting in a more natural sounding speech. Compatible with phones and mobile networks supporting HD Voice.
