If you're looking to pay for a pair of cans what most would pay for a stereo system, then these are the bad boys for you. The Sennheiser HD 820 is handcrafted in Germany, for audiophiles, using state-of-the-art technologies, including the use of glass components for sound so realistic, it's unbelievable. The noise cancellation is exceptional, while those in close proximity won't be disturbed by your beats.
