Optimal Integration
Designed jointly by Sena and Shoei, the SRL and SRL2 are commuication systems tailored specifically to the Shoei Neotec Ⅱ helmet and the Shoei GT Air II respectively  – The SRL is virtually undetectable from the outside of the helmet, and functions with a simple 3-button control.
COMMUNICATION IS OUR GAME
Connectivity Simplified
A dual Bluetooth chip allows for up to 8 intercom connections as well as simultaneously listen to music and talk to other riders via Intercom using Audio Multitasking. When audio comes through the Intercom music will automatically decrease in volume, and return to a normal volume when riders stop talking over the Intercom. Simply pair the SRL with your smartphone to stream music, listen to GPS directions, and take and make phone calls.
THE SRL DOES IT ALL
A Feature Set to Keep you Moving in the Right Direction
Take your ride up a notch with the stellar feature set of the SRL. In addition to the the Universal and Group Intercom features, the SRL offers music sharing and Sena’s Advanced Noise Control technology. Smart volume regulates the volume of your music when the environment outside of your helmet changes, due to wind noise or increased speed. Built in FM radio lets riders easily scan through and save radio stations.  
VERSATILE CONNECTIVITY MAKES FOR VERSATILE CAPABILITIES
Stay connected and in control with the Sena Smartphone app
Linking the SRL with the Sena Smartphone App (for iPhone and Android) allows you to configure device settings and access our quick guide at the click of a button. The SRL can also easily connect to the Sena RideConnected App to intercom with a virtually limitless amount of riders over an infinite range, so long as you are connected to a mobile network.
