Hi @bilanz, welcome to the Sonos Community!

I’ll be happy to pass your feedback on to our team. You do have the option of purchasing a compatible white power cable from our store, however I can certainly see your point that it could come as default with the white Arc.

It may be worth reaching out to our Sales team to see if they are able to assist you regarding this

I think the design department was thinking most people have a dark media console. A black power cable blends in with a dark console. A white power cable does not.

You can purchase the Arc power cable in white:

@Xander P : I did reach out to the sales team om my country. No hjelp there. No option to buy this in my Sonos story in my country. 
@Stanley_4 : unfortunately Amazon does not deliver this to my country (Norway)

@GuitarSuperstar: If color matching to black media consoles is a design choice, why develop a white Arc in the first place

Here’s the link to the white power cable for Norway: https://www.sonos.com/no-no/shop/power-cable-i.html
