Consider a Sena SMH10. It’s one of their basic units and is fairly inexpensive (<$175 US). It allows you to connect to your cell phone wirelessly for hands-free calling, plus you can listen to music on your phone if you’re so inclined, all with voice commands or by using the large jog wheel and buttons. Its intercom features are fairly basic and runs on Bluetooth 3.1, hence the lower cost. Comes with microphone, helmet speakers, rechargeable battery, and a charger.
