An error has probably crept into our specification, I will fix it as soon as possible. Thank you very much for pointing this out!

The Beosound A1 2nd Gen is not ideal for permanent mains operation as it is designed as a battery-powered speaker. However, they can be paired in stereo mode, which is suitable for playing classical music and rain sounds. To do this, the speakers must be paired manually or via the app. However, for a permanent power supply, they would need to be connected to an external power source, which is not the original purpose of the product.

This is now normal for electronic products, which have no regular successors and are popular, that prices no longer really go down. This enormous fluctuation is caused by fluctuating availability and changing market prices.

This is because different variants, in this case color-variants, can have different prices due to deviating purchase quantities, prices or other reasons.

The manufacturer does not seem to provide any information on this. I would ask the manufacturer directly.
