Head protection that lets you chat while you ride
While riding in a group, having the ability to chat to each other can make the experience better. SENA's R2 Evo cycling helmet is equipped with Mesh intercom for you to coordinate with your fellow riders or to simply have a chat. The difference between a Mesh intercom and a Bluetooth intercom is that it doesn't depend on one user in order to establish a connection to everyone.
On a Bluetooth intercom, when one user is disconnected for some reason, another user connected to him is disconnected. In a Mesh intercom, one user can be connected to multiple users closest to him while another user is also connected to multiple users nearby.
Lets just say a Mesh intercom has a much more robust connection than Bluetooth intercom. A Mesh intercom can also connect more users and can have different channels up to 9 to separate users much like a radio channel. The range of SENA's Mesh intercom is about half a mile (900 m) and groups can be created with the smartphone app.
Audio is delivered through integrated speakers just above the ear and doesn't interfere with the rider's ability to listen to the surroundings. The microphone built into the front of the helmet has Noise Control technology to transmit voice clearly. You can use the Bluetooth 5.2 to connect to your smartphone for calls, GPS navigation, and audio.
As for safety, the R2 Evo comes with a built-in taillight with 3 brightness settings for different lighting situations. The helmet is made of in-mold polycarbonate shell and lined with washable inner padding. It complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 5 and Older.
