I bet he's listening to black metal
Sauron Helmet Headphone Stand

Sold by Etsy shop ObjectWorks for $57, this is a 13.8″ headphone stand in the form of Sauron’s helmet, printed from plant-based plastic. Available in black or grey, it makes the perfect addition to your Hobbit Hole themed gaming room. Or a messy nightstand (perfect for late night impalements). Can you imagine if Tolkein had opted for using the Ear Of Sauron instead of the Eye? “Or the nose!” Like Indiana Jones picking the Holy Grail at the end of The Last Crusade, he chose wisely.
