Sena Technologies, Inc. provides Bluetooth headset and intercom systems for virtually every kind of rider and at a variety of price points. The company's entry-level unit, the SMH5, allows the rider to become connected wirelessly to his or her Bluetooth enabled mobile phone, GPS, mp3 player and more, plus another rider or passenger via intercom. Sena's flagship unit, the SMH10, does everything the SMH5 does, and allows the rider to communicate via intercom with three other riders or passengers. Virtually all communication and function control can be done hands free utilizing the system's voice prompts. Sena will also soon be releasing a Bluetooth headset/intercom designed especially for half helmets.
