FenderTalk

FenderTalk turns your phone into a motorcycle intercom system like Cardo, Sena, and Vimoto etc. It deploys a local WiFi network between devices to carry out voice communication, which means it does not depend on carrier network infrastructure and you can chat with your partner in the most remote areas. When chatting with your passenger or other riders, I recommend to use a pair of Mic built-in bluetooth earbuds because it can offer excellent noise-cancelation and wind-resistance. Together it will outperform those professional intercom systems mentioned above.
