This Air-band Transceiver Connects wirelessly via Bluetooth to your Sena equipped helmet directly without use of any addition items. 
Note: If choosing this product, the base Vector 5 helmet can only connect to one Bluetooth device at a time (Cell Phone or this 2-way radio) If you want both devices to be connected at the same time, upgrade to one of the SENA 10 options available in the store.
This Bluetooth Two-Way Radio allows you to use your existing SENA Bluetooth to listen to your music, talk on the phone, and have wireless connectivity to this two-way radio device via Bluetooth. This package comes with the Two-Way Radio. When transmission comes in, your music or phone call will be interrupted by the two-way radio call, or use the optional PTT button "which can be mounted anywhere including a throttle grip" to speak with local traffic or ATC.
