Digital radio reviews: Features explained
Features to look for on a digital radio
Digital radios have various different features, from EPGs to pausing and rewinding live digital radio broadcasts. While some of us just want a basic digital radio for listening to music in the kitchen, others prefer the versatility that some of the more feature-packed digital radios can offer.
Here we give jargon-free explanations to help you decide which features are worth paying extra for when choosing a digital radio. You can check out the Which? Best Buys for the best digital radios, and compare digital radios with our interactive product finder to find a model to suit your needs.
Not all digital radios can tune in to FM
Tabletop digital radios
FM on digital radios
Most digital radios can also tune in to FM radio, but not all do – something to consider if you take your digital radio to a remote holiday spot where there's no digital signal.
If you already have an FM radio, and you're buying a digital radio for a different room, be aware there's a small time difference between analogue and digital broadcasts – a minor irritation if you have both radios on at the same time in different rooms.
Electronic programme guide
An electronic programme guide (EPG) allows you to select a digital radio station and scroll through to see future programmes.
You can get it to set reminders – for example, to set your digital radio to switch to Woman's Hour at 10am, or even record an upcoming show. It works in a similar way to the EPG you get on your Sky or Freeview set-top box.
The technology is still in its earliest stages and only the BBC provides the data needed to update the EPG – so you can only look up BBC programmes. We expect EPGs to improve as digital radio manufacturers get to grips with this new technology.
Pausing and rewinding live broadcasts on digital radio
Many of the latest tabletop digital radios let you 'pause and rewind' live broadcasts. This is a great feature if you want to restart a song, say, or the doorbell rings during a crucial scene in The Archers.
Be aware that digital radios with this ability tend to run the batteries down faster, as radio data is continually stored in the internal buffer.
Compare digital radios with our interactive product finder to find models with this feature.
Recording digital radio
Some tabletop digital radios can record to the radio's internal memory or a memory card. It's worth checking how many programmes can be saved. Some digital radios can preserve more than one, but others wipe over any previously recorded material.
Digital radios with two speakers give stereo sound
When recording DAB programmes to a memory card or to internal memory a good rule of thumb is that 1MB can store one minute of DAB radio for stations broadcasting at 128kbps, which most do.
Digital radios with stereo sound
If you want stereo sound, choose a tabletop digital radio with two speakers. Obviously, the stereo effect on portable digital radios is limited because the speakers are close together.
Some mono models will allow you to connect your digital radio to your hi-fi to listen in full stereo glory.
Presets
Digital radios tune in automatically to all the available stations when you first turn them on. You can then scroll through the names of the stations and store favourite stations as presets.
Clock radio functions on digital radios
Lots of digital radios have the same functions a clock radio: a clock and alarm, as well as 'snooze' and 'sleep' functions. But most are not a perfect substitute for a proper clock radio because the clock digits are usually small, and not necessarily illuminated.
Pocket digital radios
Good headphones improve digital radio sound quality
Headphones
All pocket digital radios are supplied with a set of headphones, but even the best offer only average sound quality.
To find a good pair of headphones which can improve the sound quality, check our headphones reviews.
FM on pocket digital radios
Most pocket digital radios can receive FM signals as well as DAB. None of our currently tested pocket digital radios can receive AM, though.
Pocket digital radios with MP3
Several pocket digital radios can also double as an MP3 player. Some record to their internal memory, others to a memory card.
Maximum volume
Some pocket digital radios have a maximum volume exceeding 100 dB, which is above the level which can damage hearing, so take care when listening on a loud setting.
For more information on hearing damages check the British Tinnitus Association links page which will give you a range of options.
