You can listen to radio in different ways. You can buy an older radio that only supports FM radio, but newer models often have more functions. A digital DAB+ radio lets you listen to noise-free radio. An internet radio can receive thousands of international radio stations. Some radios have a built-in alarm function. If you want a clock radio, choose a radio with this function. There are also radios with a battery. In most cases, you can take it with you on the go.
