Ive got a pocket DAB Roberts digital radio, that operates on two AA battery's, its also has analogue radio as well.
The Ariel is the headphones, you plug into the headphone jack.
Its small enough to hold in the palm of your hand, so is very portable, and has an amazing signal for something so small., getting a signal in remote areas of Scotland may be an issue, but it works a treat in remote areas of Snowdonia.
Ive listened to classic FM, on Carnedd Lewellyn and Diffwys, and have never failed to get a decent signal, but its not waterproof, so only gets taken out in fine settled weather.
