Sena SR10 Two-Way Radio Bluetooth Adapter

The SR10 Bluetooth Adapter allows you use any of our headsets with your handheld radio onboard -- and communicate wirelessly between your handheld and your 2Talk or Sena headset. HANDHELD RADIO NOT INCLUDED. CABLE SOLD SEPARATELY. How does it work? The SR10 adapter allows you to add Bluetooth functionality to your handheld radio so that your handheld can now communicate with your headset wirelessly.  So, you can easily hear and talk via your wireless headset to the 2-way radio.  The SR10 Bluetooth adapter is worn on your belt, and the headset is on your head.  A short cable (sold separately) connects your handheld 2-way radio's Speaker/Mic/PTT port to the SR10 Adapter, and the headset is connected wirelessly via Bluetooth to your radio.   The SR10 Adapter has its own PTT button that is used to open the mic input to your radio.  It also includes a separate plug-in  PTT button on a curly-cord cable should you wish to have the button conveniently mounted elsewhere.   Why would I need it?
