MX Controls proudly Introduces the worlds first "USB Headset HUB". This HUB allows any 2 USB Headsets(Wired or Wireless) to be plugged into it. The users of the Headsets can then directly talk to each other as well as to an externally connected analog device at the exact same time. While the users are talking to each other, they can also simultaneously listen to either an optical or analog connected source device. The MX1 is powered from its internal rechargeable battery or from its micro USB connector. The micro USB connector is also used for charging the internal battery and installing firmware updates.
