Ok, calculating the import taxes gave me a different result (this time more pleasant).
Setting the value of the imported product to $225 USD, shipping to $0 USD became about $290 USD (in sweden). It was the same for product value 200 and shipping 25, somehow I've miscalculated it horribly wrong earlier.
This import price is 100% acceptable as it brings the K7XX's well under the price point of the fidelio X2's (again, in sweden).
[edit]: After some quick research I found out that the website that gave out exchange rates to the customs calculator were wonky that day (I thought it was strange seeing the exchange curve twisted in a square loop)
