The Sonelco “Easy Series” combines a series of products designed to make sound installation simple and easy. An essential feature of the range is its direct supply to mains (230V).

There are also models with Bluetooth technology so that it is possible to listen to music from smartphones, tablets, computers, etc., without having to use a cable connection.
