Headphoneus Supremus
Ordering (expensive) headphones from Amazon is a bad (and dumb) choice. I once bought an expensive speaker and when it got delivered, you could clearly see the seal has been removed to be replaced by some 'fake OEM' seal. And the flip cover, you can easily feel and see the dense in the middle. And the worst? It was advertised as New. Fortunately I got my refund. Better order headphones from authorized web/stores.
