The Sena 20S Evo units turned up today, very good service from Sportsbikeshop.
This is what they looked like in the box.
They came with lots of, foams, Velcro pads and leads. There are lots of fitting and adjustment options.
So far I have only tried them in the house. The sound quality is better that the Scala G4s and the volume is louder by a fair bit.
As with all new gadgets it will take a while to get used to all of the functions, but I have the phone, sat nav and intercom working, which is all I need for now.
I will report further when I have something to report.
I would like to try the range and will have to figure out how to do that, it might mean getting Melanie to wear her helmet in the car.
