Yes, Dr. Dre Beats! Those ridiculously expensive headphones that I've only worn when I go into Best Buys, or when my brother is nice enough to let me borrow his pair. It seems like Parisians love their Dr. Dre Beats and with good reason- they completely block the sound which comes in handy when you're commuting in the metro or simply want to ignore everyone.
So if you want to look like more like a Parisian just have your headphones on (preferably Dr. Dre Beats) when you're in the metro, the bus, or when walking on the streets of Paris.
PS. They make a great 22nd birthday/Christmas gift. *wink wink*
