Cool new loudspeakers from ednet! Not just good sound, but a sensational little show too. Coloured columns of water dance to the rhythm of the music you select. It’s just a bit of fun and it will certainly put you in a good mood. But what colour should you go for: stylish white, cool black, or be a bit more daring and go for a bright pink? A cool Christmas present, or a nice little gadget as a treat for no particular occasion.
