I remember seeing radio receivers similar to these when I was younger. The one on the right is very similar to a radio my parents had. The one on the left resembles a radio my grandparents had. It had a mighty sound and took some time to warm up before there was any sound coming out of it.
A radio nowadays looks either similar or very different from those above. There seems to be a keen interest in old-style radios as well as new shapes like this one:

But what's a radio compared to a Smartphone. It's just one of a Smartphone's functions. Smartphone is what you use now to listen to music.
