Recommend a radio tuner

Hey there,

I got this crazy Idea that I would like to listen to radio from time to time, I was thinking buying all-in-one unit, but I thought a bit more and I realised that I don’t need all-in-one unit, because I have Marshall Kickburn 2 and which is sufficient speaker and it hack 3.5mm jack and I just need to find an FM radio that is decent quality.

Is there something out there that I can pair with the kickburn speaker?
