I live in Denmark so usually placing my orders within the EU to avoid extra import tax and customs fees etc. 
Unfortunately only a few danish resellers have the high end Sennheisers and for some reason they are always out of stock or available in 1 out of 27 stores, so you would have to drive to the other side of the country to see / demo them.
My last 4 orders have been placed with Audutorium.de i Germany - Great assortment, friendly staff, quick shipment of orders and now popcorn - What’s not to like
