On the Digitec website you can choose two products and "compare" them. If you believe the information on Digitec about these two products, the more expensive version has slightly more powerful speakers (35 vs 20 watts). Otherwise, it's probably best to compare the manufacturer's data

After much research on the internet, I can confirm that it is "only" the colour. With the competition, the price differences between the coloured models are hardly present. Both articles have 2x 20 watt stereo speakers + 1x 30 watt for the subwoofer.

The colour (for whatever reason this is CHF 84.-).
