I looked up on the web for intercom systems and saw the Interphone symbol, i myself use a scala G9, i dont know how good the Interphone system is so you will just have to look up any reviews concerning it
Interphone are one of the big 3 in bike intercoms - slightly behind Sena and Cardo. If you are planning to talk to your mates, then it is a good idea to buy into the same brand as them.
