When was the last time you really sat and listened to your favorite piece of music? With Denon's line of Music Maniac headphones you'll want to do it again, and again, and again. Some people are just as obsessed about sound quality as we are. And they know sound quality is much more than the size of the driver and the cavity space in the ear cup - it's further enhanced by the right cables, the right connectors, the right tuning. At Denon we've sweated the details so you don't have to.
