This is probably the most stylish clock radio you can get at the moment. It looks a bit retro, quite minimalist, and is very nicely made. The unusual design means it's also easy to get hold of if you need to move it.
Its predecessor, the 705, had a bad reputation for waking you up at midnight. Fingers crossed, the 706 doesn't share this trait!
The main difference (if the styling around the display looks different in the photo - it isn't in reality) otherwise from the 705 is somewhat academic in the UK: the 706 can receive DAB+ transmissions. This potentially future-proofs your clock radio, but it's looking pretty unlikely that the UK will ever switch to the superior DAB+ format, even though the rest of the world is adopting it.
Never mind. That's not going to affect clock-radio users much.
This Sony does radio perfectly well. The sound is entirely adequate for a bedside radio: it's clear and crisp, which is the most you can ask from a small speaker. Setup was automatic and extremely quick. Reception has been fine until the recent humid weather when I had to fiddle with the wire aerial to get clear sound (oddly, the aerial needed to be below the radio rather than above it). You can use FM radio too, if you want, but there's no RDS, surprisingly.
I found the controls very simple and logical, and only had to refer to the instructions to see how to set radio presets. Setting the alarms means running through a sequence each time, which could be annoying if you wanted to change settings often. But in practice, you probably set the alarms once and forget them, especially when you can set four different alarms to come on every day, just weekdays, just weekends, or on one specific date (this is the advantage of DAB radios and extremely useful).
The display has three brightness settings. If you're like Goldilocks, and me, you'll probably choose the middle setting. The dimmest is almost too dim to actually see unless it's pitch black, but the brightest makes a great night light.
It's a nice clear, big display. Scrolling text doesn't blur, though as usual on DAB radios, it scrolls far too slowly.
The power supply is separate, in the plug, but for once it's small and neat, not a huge brick.
The Sony 706 isn't perfect though. If you're in bed you can't see the buttons on top of the machine because they're angled away from you. So you either have to get half out of bed or learn to do things by touch alone (there is a tactile dot next to the volume up button but otherwise the buttons all feel the same). And although you can (very usefully) set the volume of the radio for each alarm setting, you can't choose which radio station comes on - it defaults to the last used station.
These are small points though. The bottom line is that this is a very attractive clock radio with clear sound, many useful functions, and an excellent display.
