Super bass Bluetooth speaker

[Android Question]

Some of these have an fm radio built in are or is this an actual radio and how do you control it. I have one with no fm and was looking at some that say it is an fm radio. the pictures show nothing that controls the radio. Do you know how this works?

There's an FM radio in the ones that have FM radio built in. The others will play the FM radio that's built into the phone.
