"Designed jointly by Sena and SHOEI, the SRL is a communication system tailored specifically to the SHOEI Neotec Ⅱ helmet, the upgraded version of the wildly popular Neotec modular helmet. The SRL is virtually undetectable from the outside of the helmet and functions like our top selling 20S with a simple 3-button control."
Trialled on our recent NZ trip, I'm happy to report that even I can instal and use it.
Sena's Blurb continues
A dual Bluetooth chip allows for intercom with up to 7 other riders as well as Audio Multitasking to listen to music and talk to other riders via intercom simultaneously. 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 your SHOEI helmet communication system with your smartphone to stream music, listen to GPS directions, and take and make phone calls.
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.
